How Quartz Tube Stations Work and the Benefits They Provide

Among the many processing steps involved in the manufacture of semiconductor components are high-temperature operations such as diffusion of materials into the silicon wafers. Quartz tubes are an ideal vessel for these process steps because the tubes can withstand the temperatures required and are inert enough to minimize contamination.

Typically, the silicon wafers are placed into a horizontal quartz tube large enough to hold the wafers and their supports. The quartz tube cleaning station can heat the contents up to over 1000 degrees centigrade. In a diffusion process, impurities such as phosphorus are introduced into the quartz tube.

Once the process is complete, the quartz tube is contaminated and has to be cleaned for the next batch of wafers. Complete and reliable cleaning is essential for the semiconductor manufacturing process because contaminating particles can cause defects in the semiconductor components or result in inferior product quality.

How Quartz Tube Cleaning Works

Quartz tube cleaning is a custom-designed process because the dimensions and cleaning requirements of quartz tube furnaces can vary widely. Quartz tubes are mechanically delicate, so they have to be handled with care. At the same time the cleanliness requirements are rigorous so that all traces of the contaminating material have to be removed. Finally, the rinsing and drying process must not introduce any new particles into the quartz tube. The cleanliness of the tube directly impacts the performance of the semiconductor manufacturing facility.

In horizontal quartz tube cleaning stations, the tube is inserted into the cleaning enclosure and cleaned with an acid spray. The acid dissolves and removes the contaminant from the high-temperature furnace. A subsequent rinse cycle removes all traces of the acid from the tube surfaces. A drying cycle can speed up drying without introducing particles into the cleaning enclosure. Mechanical handling of the tubes reduces the possibility of breakage due to human error and minimizes opportunities for the entry of contaminating particles. Safety interlocks, exhaust fans and safety shields protect operators from the hazardous chemicals.

Modutek’s Quartz Tube Stations Offer Numerous Benefits

A key factor in effective customization of quartz tube cleaning stations is that the supplier has to design and build the stations so that they can make the required adjustments. Modutek designs and builds all process, etching and cleaning components in house at the company’s San Jose, California facility. Equipment is customized exactly according to the requirements of the specific application.

In addition to providing customized equipment, Modutek can supply the degree of automation required by the customer. Cleaning process steps can be initiated manually or the whole cycle can be completely automated. Different steps can initially be run and timed manually and then, when optimum performance is reached, automated operation can be locked in.

Full automation reduces human error and keeps operators safe by allowing them to monitor the cleaning process remotely. Automated quartz tube cleaning stations will run the same cleaning job exactly the same way, with identical timing and dosages. Results from an automated system are predictable and uniform and the system can be programmed for the best possible results.

Modutek’s horizontal quartz tube cleaning stations are an excellent solution for semiconductor manufacturers. Rugged and reliable with one-piece construction up to ten feet long, the basic units offer many options for additional features. Once the requirements of the cleaning application are satisfied, Modutek can offer design add-ons such as holding tanks, automation features, a T/C sheath cleaner or a bottle washer. Modutek is a leading semiconductor equipment manufacturer that provides continuous product innovations and improvements along with the highest degree of customer service and support.

How to Qualify Which Semiconductor Equipment Manufacturers Meet Your Requirements

how-to-qualify-which-semiconductor-equipment-manufacturers-meet-your-requirementsThere are a number of things to keep in mind when you review which supplier to use from a list of semiconductor equipment manufacturers. From the ability of a manufacturer to customize solutions to meet specific client needs, to company reputation, the quality of the equipment sold, and after-sales support, there is a lot to consider. Only after you create a shortlist of potential companies to work with should you consider pricing and other minor details.

The Customization Question

Whether the need is to upgrade lines or replace old equipment with new machines, every semiconductor foundry or research facility is different, and comes with very specific requirements. Often, equipment newly purchased needs to be able to interface with systems already in place, and at other times, space or system size concerns override all other areas of consideration.

Equipment may also need to be internally customized with specific feature additions in order to be able to deliver on client requirements. Equipment manufacturers need to provide extensive experience and expertise with such customizations. Before a specific semiconductor equipment manufacturer can be chosen, they need to be able to demonstrate that they are able to work with clients, and to supply systems that are customized to their needs.

Reliability of Equipment

Once equipment has been purchased and set up, it needs to stay online for long stretches of time with minimal downtime. The best way to determine if a manufacturer is able to supply equipment of such description, is to contact references and study reliability statistics. Suppliers should be asked to furnish detailed information on scheduled downtime requirements, and logbooks obtained from actual installations.

After-Sales Support

Equipment warranties and support capabilities are the last item on the list to look at before a contract is signed with a selected supplier. Warranty policies should be simple and straightforward, and yet be comprehensive in describing what’s covered. All new equipment should typically come with at least a one year warranty.

It’s also important to check on the strength of every company’s service department. The most generous warranty policy would not be of much use if there were few personnel able to deliver on it. If there are third-party service providers that are on call, rather than an in-house department, it might be a warning sign that the manufacturer is not well-equipped to deliver a quality after-sales experience. Since third-party service providers usually deal with products from multiple companies, they are not likely to be as expert in their fields as in-house personnel. The best way in which to check on a company’s service ability is to simply call with a question prior to purchase.

Use a Supplier with a Proven Track Record

Finding the right equipment supplier is a vital step in the set-up of a semiconductor manufacturing facility or research center. The equipment from a supplier will affect future productivity, and quality of output. Since many suppliers have come and gone over the years look for one that has a proven track record that has been around for awhile. In addition the systems and equipment they sell should be continually improved to keep up with the latest technology and allow for easy upgrades.

Modutek’s Experience, Expertise and Longevity

Modutek has over 35 years of experience as a semiconductor equipment manufacturer, and has continually operated during that time to improve their equipment and address the needs of many clients. Not only does Modutek design and assemble their own equipment, all their software is designed in-house as well.

How Robotics Have Revolutionized Semiconductor Manufacturing

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

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.

Designing Semiconductor Manufacturing Equipment for Ergonomics and Safety

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.

How to Select a Supplier from Your List of Semiconductor Equipment Manufacturers

How to Select a Supplier from Your List of Semiconductor Equipment ManufacturersWhen choosing a supplier from a list of semiconductor equipment manufacturers you have to look at a wide variety of factors. Key points to evaluate include the following:

  • Customization capabilities to meet customer requirements
  • Equipment reliability
  • Company experience and expertise
  • Warranties
  • Service and customer support

Only after you have determined which manufacturers can actually supply the equipment you want can you look at cost of ownership and pricing to make your final decision.

Specifying What You Need

Semiconductor fabrication lines and research labs are different and have specific requirements when they want to upgrade lines, replace components or buy new equipment. Sometimes the purchased equipment has to interface with existing systems, sometimes space is a factor and sometimes the physical set-up of the production facilities limit what can be installed. A supplier has to be able to evaluate these constraints and suggest solutions. The equipment proposed often has to be customized to some extent and the supplier has to have the experience and the capability to adapt his standard solutions to particular situations.

Equipment Reliability

Once you have purchased your equipment, it has to keep working with a minimum of downtime. The best way to evaluate the reliability of a supplier’s equipment is to ask for references and reliability statistics. Suppliers should submit normal hours of scheduled downtime, estimates of unexpected downtime and the records of actual installations. Once you have narrowed down the list of suppliers, it’s a good idea to check with some of the references who are not direct competitors of your company and verify what the supplier has submitted.

Warranties, Service and Support

Before you sign a contract with a selected supplier, check on his equipment warranties and his service and support capabilities. Warranties should be simple, comprehensive and of sufficient length. Check on whether the supplier has enough service personnel. Also important is whether he can rely on his own personnel to carry out service or whether he has to call in third parties. If a supplier subcontracts a lot of his equipment manufacturing, he is less likely to have competent service personnel on staff to deal with that equipment. Call support to see how they respond to support requests. Often calling a supplier’s customer support line with an equipment question rather than going through your contacts in sales will give you an idea how well a supplier responds to support requests.

Conclusion

The selection of the right semiconductor manufacturing equipment supplier for additions to a fabrication line or a research lab affects future productivity and output quality. You have to make sure you buy the equipment you need and select a supplier who will keep it working optimally.

Modutek has the experience required and the expertise to advise customers and to support their installations.
