Why Preventative Maintenance of Wet Bench Equipment is Important

Posted on by

Why Preventative Maintenance of Wet Bench Equipment is ImportantTimely preventive maintenance of wet bench equipment allows semiconductor manufacturers to avoid costly unexpected downtime due to equipment failure and quality issues. Wet bench equipment is complex and is typically used in a demanding manufacturing environment. Calibration, cleaning and replacement of parts that wear out has to be performed regularly to maintain facility performance and output quality. Once scheduled, preventive maintenance has to be carried out quickly and professionally, completing the required tasks on time and using personnel with the required expertise. If the necessary preventive maintenance is not completed or is not done correctly, poor quality products, equipment damage and compromised worker safety can result.

Scheduling Preventive Maintenance

Wet bench stations operate with corrosive chemicals while at the same time relying on the highest standards of cleanliness and control of contamination. Chemical dosages and control of variables such as temperature are critical for a successful production line. Some components have to be changed, cleaned or serviced regularly while others have to be inspected to see if any action is required.

The semiconductor manufacturing equipment supplier will often specify what preventive maintenance measures are required and which ones are recommended. Some tasks can be carried out by the semiconductor manufacturer’s personnel, but others will often require specialists from the supplier. Developing an overall schedule that limits downtime for the production line to a minimum while ensuring that all preventive maintenance tasks are scheduled and carried out can be challenging.

Carrying Out Preventive Maintenance

Depending on the details of the semiconductor manufacturing operation, some preventive maintenance tasks can be performed while the line is in operation. For some lines, production steps are sequential so that a particular piece of equipment may be at rest for a given period. Preventive maintenance can then be carried out on that equipment.

Other parts of the production line may be in more or less continuous use for periods exceeding the recommended preventive maintenance interval. In such cases the required downtime has to be factored into the production schedule with reduced throughput. When all these factors are taken into account, it becomes clear that preventive maintenance for wet bench equipment may have to be flexible and reactive to manufacturing requirements rather than based on a fixed schedule.

Coordinating with a Competent Supplier

Developing an ongoing wet bench preventive maintenance program is easiest when partnering with a supplier who is familiar with the installation and who can handle all preventive maintenance tasks, even if the stations are highly customized. Such a supplier can help the semiconductor manufacturer develop and adapt a suitable schedule and help complete the work. The supplier can offer to carry out those tasks that specialists can perform quickly and competently while giving instructions for on-site semiconductor manufacturing personnel to complete simple tasks and inspections. Such an approach is ideal from the facility owner’s point of view.

Modutek can offer this type of field service and customer support because it has in house expertise based on almost 40 years of experience in the wet processing technology field. Scheduling and carrying out preventive maintenance on wet bench stations while keeping disruptions to production at a minimum requires such experienced personnel.

In addition to highly qualified specialists, Modutek designs and builds all its own wet bench stations at its manufacturing facility in San Jose. As a result, it can offer first-hand service, repair, and upgrade support without having to call on third parties. Working with a competent partner such as Modutek helps customers carry out the necessary preventive maintenance that keeps their equipment functioning at an optimum level while reducing downtime and avoiding compromised product quality.

New SPM Process Provides 75% Improvement in Chemical Savings

Posted on by

new-spm-process-provides-75-improvement-in-chemical-savings2

Earlier this year Modutek started implementing its new SPM process with automatic adjustment of the sulfuric peroxide mix concentration and the company now has benchmark results from real process applications. Normally the SPM mixture deteriorates continuously as the hydrogen peroxide turns to water and dilutes the concentration. The SPM mixture has to be completely replaced every eight hours or so at the outside. Costs are substantial for downtime during new mixture pour and for the replacement of the chemicals as well as for neutralizing and disposing of the corrosive mixture in an environmentally safe way. Trying to lengthen the period during which an SPM mixture can be used has been an ongoing process for many companies but without results that provide a safe and reliable alternative.

In the Modutek “Bleed and Feed” system, a “dirty” tank and a “clean” tank are used to continuously compensate for changes in the mixture concentration caused by the degradation of hydrogen peroxide. Periodically when needed, a programmable amount of mixture is drained from the dirty tank and another programmable amount of mixture is automatically transferred from the clean tank to the dirty tank. To compensate, an appropriate amount of sulfuric acid is added to the clean tank and both tanks receive enough hydrogen peroxide to restore the concentration. The “Bleed and Feed” process is designed to maintain the SPM mixture concentration automatically over extended periods.

Benchmark Results from a Real “Bleed and Feed” Application

One of Modutek’s customers that use their semiconductor manufacturing equipment now has real-life results from the use of the company’s “Bleed and Feed” SPM process improvements. The results show significant reductions in chemical use, downtime for re-pour and disposal volumes. Detailed results are based on a 2 6-inch carrier bath size with an 8-hour shift and are as follows:

  • Volume of sulfuric acid used reduced by 77%
  • Chemical disposal volume reduced by 75%
  • Acid neutralizer use reduced
  • Acid re-agent use and cost reduced
  • No downtime to drain and re-pour
  • System drains reduced from three times a day to once a week
  • Increased throughput
  • No original process result changes
  • Increased safety due to less operator interaction with dangerous chemicals

While other companies have tried to develop other SPM clean process improvements involving less chemical use, Modutek’s system is now proven to provide excellent results in real life applications and operate reliably.

Improved SPM Process in Custom Designed Systems

While Modutek has developed a greatly improved method for maintaining SPM process mixture concentrations and reducing chemical use, the new method can be applied in any custom-designed SPM process wet bench. Modutek designs and assembles wet bench products and semiconductor manufacturing equipment at their facility in San Jose, California and can supply systems that exactly meet its customers’ requirements.

Process engineers and facility managers concerned about the environmental impact of high toxic chemical use and the increasing costs of chemicals such as sulfuric acid can contact Modutek for a free quote or consultation to discuss solutions to these issues. Modutek can suggest wet bench systems and follow up with proposals from their complete line of wet bench products. If the SPM process is needed by a customer, Modutek now has the benchmark results on reduced chemical use and improved facility operation.

 

How Robotics Have Revolutionized Semiconductor Manufacturing

Posted on by

The automation over the last 25 years of wet bench stations used for semiconductor manufacturing has resulted in more efficient production and an increase in output quality. When the handling and mixing of the chemicals, the handling of the silicon wafers and the timing of the process steps were carried out manually, mistakes could result in defective products. Semiconductor equipment manufacturers have developed automation that has resulted in improved yields and less waste.

Modutek has been on the forefront of developing robotics and process control software that allows fully automatic or semiautomatic processing of silicon wafers. In this way, the entire semiconductor manufacturing process is controlled accurately and reliably. Chemical quantities and process timing are precise, process parameters are reproducible, and material handling is safe. Contamination is reduced with robotic wafer handling. For all these reasons, adding robotics to a wet bench processing line is a cost-effective solution for better facility performance.

Modutek’s Leadership in Wet Bench Robotics

During the company’s history of making wet process equipment, Modutek has focused on the integration of the latest technology in-house and with its own team of specialists. Founded in 1980, Modutek manufactured components such as quartz heated baths, nitride etch baths and rinsing systems. In 2002, Modutek acquired Sysmax Inc. with its advanced automation technology and from there developed its own robotics.

Advances in robotics have allowed Modutek and other semiconductor equipment manufacturers to offer semi-automated and fully automated stations. These wet benches and chemical stations can control the whole semiconductor manufacturing process with no or limited operator intervention. Both fully automated and semi-automated stations produce excellent process uniformity with semi-automated stations and robotics available at a lower cost if full automation is not required.

A key Modutek advantage for this type of equipment is that all process control software and robotics are designed and assembled in-house. The team working in the company’s San Jose, California manufacturing facility carry out all development work for both the SolidWorks Simulation Professional and SolidWorks Flow Simulation software and for the associated robotics. All silicon wafer fabrication equipment is also tested in-house using de-ionized water. As a result, Modutek can offer unparalleled support and customization services.

Advantages and Benefits

The primary motivators for installing fully automated wafer fabrication equipment are to reduce costs and improve output quality. Elimination of human error and increased precision of chemical use means less waste and high-quality products.

Modutek’s SolidWorks Simulation Professional and SolidWorks Flow Simulation software can calculate correct dosages and track chemical usage. With tighter environmental regulations, efficient chemical use not only reduces costs directly but also makes environmental compliance easier and less costly. When the composition of chemical baths is tightly controlled, the etch rate or wafer cleaning is predictable and consistent.

Automatic chemical delivery is not only more reliable than a manual procedure – it is also safer. Spills of hazardous or corrosive chemicals are less likely, and employee safety is increased.

Robotic handling of wafers can reduce contamination and deliver cleaner wafers for subsequent processing steps. The reduced size of features in semiconductor microstructures means that a single particle can block etching of a key feature or impact doping in a critical part of the semiconductor component. It is vital to keep contamination of wafers to a minimum, and robotic handling of wafers reduces the sources of particle contamination.

While some semiconductor manufacturing applications can be automated with standard solutions, in many cases the particular needs of a specific customer can require a degree of customization of the robotics and the process control software. Because Modutek does its own robotics and software design, developing custom applications is never a problem. Modutek’s team knows exactly how each part of the automated systems work and how to make the necessary adjustments.

With Modutek’s more than 35 years of experience, the company continues to promote innovation in robotics for semiconductor manufacturing. Robotics has made the wafer fabrication process more efficient, more predictable and safer. With its complete line of automated equipment, Modutek continues to bring these benefits to customers.

Advancements in Wafer Fabrication Equipment Improve Semiconductor Manufacturing

Posted on by

advancements in wafer fabrication equipment improve semiconductor manufacturingWhile the requirements for high precision control in wafer fabrication have increased, improvements in the fabrication equipment have also kept pace. The higher complexity and smaller size of semiconductor structures require extremely precise process control to ensure adequate output quality and a low component rejection rate. Advancements in automation and in reducing manual handling of the wafers have met these stricter requirements and allowed fabrication shops to increase productivity and reduce costs. Semiconductor equipment suppliers need to provide comprehensive automation solutions to meet in increasing requirements of manufacturers and research centers developing leading edge semiconductor devices.

Automation Advancements

Modutek, a leading semiconductor equipment supplier, provides wafer fabrication equipment that offers fully automated control of the entire processes. Process steps are precisely repeatable resulting in consistent output. Chemical dosage is accurate and the process is executed according to clearly defined steps. While operator intervention is still possible where needed, fully automated stations reduce errors and produce less waste.

Integrated software such as Modutek’s SolidWorks Flow Simulation and SolidWorks Simulation Professional lets operators calculate process variables and track chemical usage. Once the process is programmed, advanced robotics execute the process steps without operator intervention. Operators can rely on a consistent process environment and increased throughput with high output quality.

Both the software and the use of robotics within the automated stations themselves have significantly improved process control and efficiency. Many semiconductor equipment suppliers offer varying degrees of customized solutions for different kinds of wafer manufacturing requirements. At Modutek, both the software as well as the design, assembly and testing of their wet bench stations are carried out at the company’s facilities and are adapted to meet particular process requirements. The ability of suppliers to provide wafer fabrication equipment tailored to meet the unique requirements of semiconductor manufacturers has helped them to improve yields for each specific process they use.

Advanced Equipment Reduces Handling

The last etch process step involves etching the silicon wafer to remove the silicon oxide layer and then drying the clean wafer. Any particle contamination introduced at this point can influence further silicon wafer processing and result in defective or poor quality semiconductor components. Moving the silicon wafers from the last etch process step to a drying chamber risks introducing additional particle contamination. A new product by Modutek combines the last etch (HF) and IPA drying chamber to avoid handling the silicon wafers and substantially reduces the particle count.

The Modutek combined HF last etch and IPA drying chamber is a modified IPA dryer that allows injection of HF acid prior to the start of IPA drying. The ratio-controlled acid etches the wafers down to bare silicon and the wafers are then rinsed with DI water. Once the rinse reaches a pre-defined pH level, the IPA drying process starts with the introduction of IPA vapor from the top. The IPA or Marangoni drying technique avoids watermarks on the wafers. Throughout the process step, the wafers

Benefits from Using Advanced Fabrication Equipment

Modutek offers wet bench stations using the latest technology to improve wafer fabrication equipment and facility performance. With its advanced fully automated stations the company can improve yields by ensuring accurate processing. The software developed in house controls chemical use and precise processing of wafers. The combination of advanced robotics, dedicated software and in house expertise results in consistent, high quality output and reduced costs.

While automation drives a continuous advancement in process reliability and product quality, the elimination of the handling of wafers during transfer into the final drying chamber provides a single substantial improvement through wafer particle reduction. In recent tests only 20 particles (adders) in the 0.3 to 5 micron range were added to the etched substrate in the combined etching/drying system. This single step improvement in the fabrication process can often justify the cost of acquiring the advanced fabrication equipment that will subsequently increase facility performance and profitability.

Modutek has over 35 years of experience providing fully automated wafer fabrication equipment to the semiconductor manufacturing industry. The company has the expertise to advise customers regarding their semiconductor processing needs and can customize their equipment to meet a customer’s application requirements.

Single Wafer Processing Spurs Demand for Wafer Cleaning Equipment

Posted on by

Wafer cleaning equipment suppliers have to invest heavily in research and development to keep abreast of rapidly changing technologies and changing market conditions. Single wafer processing is one such change factor, spurring demand for wafer cleaning equipment and promising a rapid increase in market size. The wet process equipment supplier market is characterized by high barriers to entry since it requires substantial initial investment with high continuing costs. On the other hand, single wafer processing in mini-fab operations is very attractive due to flexibility and the speed with which a single wafer can be processed. As a result, the market may see additional entrants while existing suppliers try to keep up with the anticipated growth.

Wafer Cleaning Equipment Market Details

The global wafer cleaning equipment market size was about US $ 4 billion in 2016 and it is expected to grow to over US $ 7 billion by 2024. While semiconductor demand generally is fueling this growth, the use of single wafer processing is one of the factors that is behind the increasing demand for semiconductor cleaning equipment. Mini-fab facilities feature short cycle times and production lines that allow semiconductor manufacturers to quickly meet changing market conditions.

Single wafer processing uses ozonized water and hydrofluoric acid in single spin technology to reduce cycle times and increase output flexibility. As increasing numbers of operators jump into this segment of the semiconductor manufacturing industry, the demand for wafer cleaning equipment is skyrocketing.

Another factor in cleaning equipment market growth is the market for printed electronics. The technology creates electronic devices by printing on substrates and requires clean wafers as an input. Its primary advantage is low cost for high volume and the outputs are inexpensive, low-performance items such as RFID tags and smart labels.

The combination of single wafer processing and the high volume expected for printed electronics means that the almost doubling of market size over the next seven years is realistic. When electronic tags proliferate in transportation and retail and processors from single wafer mini-fabs become common in many industries that are not high users of electronics at present, the need for wafer cleaning equipment as an input for these market segments becomes clear.

Single Wafer Cleaning Techniques

Single wafer processing is only competitive when the cycle times for individual wafers are low and the output quality is at least comparable to wet batch processing. Single wafer spin processing can be used to etch silicon and provide a wet process for mini-fab single wafer cleaning. Spin processing can limit etching to one side of the wafer and can be used for wafer thinning. Single wafer cleaning is often carried out with megasonic cleaning because this method dislodges the tiniest particles and results in a low particle count for the finished substrate. As semiconductor manufacturers embrace single wafer processing, single wafer cleaning equipment is being brought out in the market.

Some single wafer processes are attractive because they deliver better results than traditional processes. Megasonic cleaning in particular can reduce particle counts for the smallest particles. The cleaning method uses megasonic sound waves in the cleaning solution to generate cavitation bubbles. When the bubbles collapse due to changing sound pressure they release energy that can free tiny particles from the substrate surface. Particle counts are often lower than with chemical cleaning methods.

Modutek’s Silicon Wafer Cleaning Equipment

Modutek has over 35 years of experience in providing the latest state-of-the-art silicon wafer cleaning and processing equipment. The company can help customers with advice on semiconductor manufacturing equipment and offers a complete line of wet processing systems. Modutek is ideally situated to benefit from the increased demand for silicon wafer cleaning equipment.

 

 

Designing Semiconductor Manufacturing Equipment for Ergonomics and Safety

Posted on by

Designing Semiconductor Manufacturing Equipment for Ergonomics and SafetySemiconductor manufacturing processes routinely use chemicals and procedures that could result in accidents if the manufacturer did not have a serious commitment to safety. Safety guidelines such as SEMI S2, published by the global industry association for microelectronics manufacturers, help manufacturers implement safe operating protocols. Ergonomic designs for semiconductor manufacturing equipment as described in SEMI S8 help ensure a safe operating environment by reducing operator strain and fatigue.

In semiconductor facilities, fire is one of the most damaging threats and burning plastic releases toxic fumes while contaminating clean areas. The Cleanroom Materials Flammability Test Protocol (Class 4910) or the FM 4910 specification allows manufacturers to specify the use of non-flammable materials for their equipment. A comprehensive approach to safety, including ergonomic design and the reduction of fire hazards is the most effective strategy for reducing accidents in a semiconductor manufacturing environment.

Prioritizing Safety When Purchasing Semiconductor Manufacturing Equipment

Installations that have been in operation for a number of years may no longer satisfy current safety standards or may not meet the safety goals of the owner. The purchase of new equipment is an ideal opportunity to upgrade existing safety features and to ensure that the new equipment is as safe as possible.

Modutek follows the SEMI safety and ergonomics guidelines to design equipment that is easy to use and doesn’t require excessive reach or strength to operate. Typical examples include the Modutek wafer holding tray and a swing-arm operator interface mount. The wafer holding tray on the Modutek wet benches includes a robot arm that moves the tray to the front of the station for optimal loading with a minimum of effort.

The Modutek operator interface is normally out of the way along the side of the station, but that position is hard to see when an operator is monitoring the process. The ergonomic design allows the operator to swing the interface out and angle it for optimal viewing. The swing arm can rotate along three axes so the operator can place it in whatever position is the most convenient. Once in position, the operator can lock it into place securely, so it doesn’t move inadvertently.

Both of these examples demonstrate how Modutek implements ergonomic designs to help operators and technicians carry out their work safely and with a minimum of effort. The result is often higher productivity, more satisfied employees and fewer accidents.

Reducing Fire Hazards on New Equipment

Traditionally clean rooms are fitted with sprinkler systems or other specialized fire protection. An array of sensors detects flames, smoke, chemical vapors or heat and triggers the fire extinguishing system. By this time contamination of the facility is severe and re-establishing clean room manufacturing capability is time-consuming and expensive.

Semiconductor manufacturers and research centers with clean room facilities can reduce the threat of a fire that could disable their production by minimizing the use of flammable materials. Many wet bench processes use corrosive chemicals in tanks and piping made of plastic or other normally flammable synthetic material. Modutek can support efforts to minimize the use of flammable materials by supplying equipment that meets the FM 4910 flammability specifications and reduces the threat of fire.

Increased Safety with New Equipment from Modutek

Modutek has over 35 years experience in designing and manufacturing wet bench stations. The company has a broad range of standard equipment and can customize all aspects of semiconductor manufacturing to meet specific specialized needs.

While Modutek wet benches have a high degree of safety and ergonomic design built in, special customer requests can always be accommodated. Specific safety features or special ergonomic requirements can be added if not already present, and additional precautions against fire and other hazards can be incorporated as needed. Modutek equipment already includes many safety features, but the company has the experience and expertise to meet any additional customer requirements.

Upgrading Used Semiconductor Manufacturing Equipment and Wet Benches

Posted on by

Upgrading Used Semiconductor Manufacturing Equipment and Wet BenchesSometimes it makes more sense to upgrade existing equipment than to buy complete new systems. Equipment may not be near the end of its useful life and new technology can often increase yield and output quality. Customers can address ongoing safety issues and reduce frequent unscheduled downtime. Upgrades can provide higher levels of automation and improved robotics can be installed.

When equipment breaks down, it may be an opportunity to replace key components while whole subsystems can be upgraded during scheduled maintenance to avoid additional downtime. By addressing known weaknesses in a production line, the overall reliability of operations can be increased. Upgrading wet bench stations and other semiconductor manufacturing equipment in this way can be a cost-effective means of improving productivity.

Specific Reasons for Upgrading Equipment

Retrofitting new components, upgrading existing equipment and repairing defective parts can often extend the life of your semiconductor manufacturing systems. Reasons for upgrading include the following:

  • Install improved technology to increase throughput
  • Upgrade components to obtain higher yield
  • Refurbish or replace equipment that is no longer supported
  • Save money by extending equipment life span
  • Accommodate larger wafers
  • Update the automatic and robotic systems and controls
  • Improve ventilation and safety
  • Upgrade electrical systems to the latest standards
  • Improve ergonomics and ease of operation
  • Improve chemical delivery system performance

Such upgrades depend on a supplier’s ability to evaluate a system’s specific requirements and implement a customized approach to install and repair components. Extensive experience with development and assembly of semiconductor fabrication equipment is a prerequisite for carrying out upgrades effectively.

Types of Upgrades Carried Out by Modutek

Modutek relies on their experience with in house development and manufacturing of wet bench and related equipment to carry out all types of upgrades, both on their own equipment and that of other manufacturers. Such upgrades can include:

  • Identifying and replacing failing parts
  • Replacing defective parts with new or retro-fitted components
  • Replacing obsolete components
  • Updating robotics, baths and wet etching components
  • Upgrading motion controls and software
  • Re-designing and improving systems within an existing footprint
  • Reconditioning existing systems to improve performance

Modutek can visit a customer’s site and perform system evaluations to develop possible upgrade, repair and retrofit scenarios. Customers can then decide how they want to proceed and Modutek can carry out the selected work.

Specific Benefits of Upgrading

Many upgrades have specific benefits associated with them and customers can rely on Modutek to carry out the work so that the expected advantages are realized. For example, upgrading controls is an effective way of improving performance. Customers can upgrade from manual or semi-automatic operation to semi-automatic or fully automatic systems to improve consistency and reduce operator errors. Upgraded controls can also reduce waste and ensure that chemical formulas are followed accurately.

Safety upgrades are often required and always reduce operator risk. Adding robotics can result in more accurate control and improved safety. When electrical systems are brought up to code, reliability often improves as well as making the systems safer. Adding ventilation, fire suppression, tank lids and fume control can improve operator comfort as well as increase safety.

Adding heaters, chillers and temperature controls can reduce process times and result in better performance. Level sensors give more accurate system feedback and adding pumps, valves and switches can result in better overall process control.

Modutek can determine whether such upgrades and retrofits make sense and then carry out the appropriate work. The company can evaluate the performance of its own older systems as well as semiconductor fabrication equipment from other manufacturers on a case by case basis that includes MEI, Amerimade, Micro Tech Process, JST Manufacturing and others. With its in house expertise, Modutek can reliably upgrade semiconductor manufacturing equipment to provide optimal performance and guarantee the results.

Modutek Receives Order for Single Chamber HF Last/ IPA Vapor Dryer

Posted on by

Modutek Corporation, a premier provider of semiconductor manufacturing equipment has received a customer order for a new innovative IPA vapor dryer. The new IPA vapor dryer includes HF (hydrofluoric acid) injection (ratio controlled) as a first step before the standard IPA vapor drying process. This provides an oxide etch to bare silicon. The Hydrophobic wafers are now rinsed to pH controlled level. Once the pH level is met the IPA vapor dry process begins in the same chamber.  This eliminates the requirement to move a cassette of Hydrophobic wafers to a separate drying station.  The new dryer system improves yields by reducing or eliminating water spots and reduces defects with particle-neutral drying.

IPA Vapor Dryer Features

Modutek’s IPA vapor dryer has a single drying chamber for DI water rinsing and IPA vapor drying. The on board HF metering ensures precision mix ratios. The oxide etch with IPA drying uses an in situ process with a rinse to pH before the IPA drying cycle begins. The system features a filter bypass for contamination control and no cassette contact points during etch, rinse and dry.

IPA vapor, generated in standard one-gallon bottles, is introduced into the drying tank through the top cover. The bottles are easy to change at deck level and the top entry of the IPA vapor ensures an even distribution. Modutek’s IPA vapor dryers handle all process sizes from standard wafer carriers to glass substrates. Modutek designs, assembles and tests all the company’s equipment in their facilities in San Jose California and does not subcontract the design or assembly of their dryers.

Modutek Dryer Benefits

Most Modutek dryer cycles conclude within 10 to 15 minutes with a very low consumption of IPA. The technology eliminates watermarks and, because there are no moving parts in the dryer, there is no chance of wafer breakage. By designing the dryer technology into the wet bench, one transfer step can be eliminated. Modutek has extensive experience with custom installations and can help design an IPA vapor dryer to meet the requirements of any application.
