How Quartz Baths Are Used in a Manufacturing Process

How Quartz Baths Are Used in a Manufacturing ProcessThe manufacture of semiconductor components requires the cleaning, stripping and etching of semiconductor wafers using corrosive chemicals in a tightly controlled environment. Two important factors for achieving improved yields of functional components are keeping the bath free from contaminants and accurately controlling the temperature. High quality quartz baths fulfill these requirements with a tank material that is impervious to the chemicals used in the baths and that facilitates fast even heating by conducting heat efficiently. A well-designed quartz bath is the most effective solution for processing semiconductor wafers in chemicals such as sulfuric or hydrochloric acids, even at elevated temperatures.

Important Characteristics of Quartz Baths

To process semiconductor wafers effectively, quartz baths must be well designed and be made of quality materials. To avoid introducing unwanted impurities into the process the bath must be made of quartz of the highest purity. It must be available in a variety of sizes and heat up rapidly, featuring tight temperature control. Operation must be safe and reliable, ideally based on extensive experience in the design and supply of these products.

Modutek Recirculating Quartz Baths

The Modutek Series QFa quartz baths are high temperature recirculating units manufactured to the highest quality standards. Modutek has over thirty years experience in designing quartz baths and the company uses the expertise acquired with this evolution to offer the best in the industry. Key qualities resulting from this evolutionary process are safety, reliability and low cost of ownership.

For its recirculating quartz baths, Modutek uses semiconductor grade flame polished quartz to keep potential contamination to a minimum. The baths feature fast, even heating and a seamless, sloped flanged design that helps ensure safe operation. Temperatures in the range of 30 to 180 degrees C. can be controlled to plus/minus 1 degree C. and the heat-up rate can be up to 2 degrees C. per minute. Bath sizes range from 7.75 x 7.75 x 9 inches to 21.50 x 11.50 x 10.50 and 17.87 x 10.75 x 14.50 inches while custom sizes are available as well.

Modutek Constant Temperature Quartz Baths

With many of the same quality and operating features as the QFa models, the quartz baths of Modutek Qa series meet the same goals of high safety and reliability combined with a low cost. The process vessel is made of internally flame polished virgin fused quartz, boron-free, and the baths have the same accurate temperature control of 1 degree C. with a heat-up rate of 2 degrees C. per minute. Options include a magnetic stirrer, a quartz bubbler and remote operation timer switches and available sizes are similar to those for the recirculating baths. Modutek quartz baths can be used with confidence to improve semiconductor processing performance.

Wet Bench Ergonomics and Safety

Wet Bench Ergonomics and SafetyImplementing ergonomic engineering principles to reduce operator strain and effort can increase safety and help prevent accidents. Established safety guidelines such as those of the Semiconductor Equipment and Materials International (SEMI), the “SEMI S8-0712 – Safety Guidelines for Ergonomics Engineering of Semiconductor Manufacturing Equipment,” can help manufacturers design their installations accordingly. Such designs make it easy for operators and technicians to reach controls and work with semiconductor wafers. Modutek follows these guidelines and has included specific features in their wet benches and other equipment to allow for ergonomic and safe operation. In addition, when dealing with specific customer requirements or retrofitting existing installations, Modutek can develop customized ergonomic solutions.

Swing Arm Interface Mount

When technicians have to monitor a process or operate tools when troubleshooting they must be able to see the operator interface and input commands safely and ergonomically without stretching or assuming unnatural positions. The normal resting location of the interface is to the side and out of the way. The swing arm allows operators to pull the interface out and over so it is visible and within reach when they are monitoring the process or handling tools.

The swing arm can rotate on three axes and tilt to let operators place it in any desired position. Once the operator pulls the interface into place and orients it in an optimal way, a single push button actuates pneumatic locking by pressing two large bearings together, preventing further movement. With this rigid and low bounce design, the interface can be positioned with one hand, and the design eliminates further movement such as might result from the operation of the touch screen.

Its epoxy powder coating and anodized aluminum finish together with its internal cabling make the swing arm easy to clean with low particulate generation for clean room applications. The fact that one technician can place the arm into a convenient position and lock it with one hand means that a second person to assist with the operations is often not required.

Easy to Load Wafer Holding Devices

The impact of safe and ergonomic design increases greatly when applied to operations that have to be carried out regularly and frequently. When wafer trays and holding devices are designed to make it easy for operators and technicians to use them, even small improvements in ergonomic design can make a big difference in both productivity and safety.

In Modutek wet benches, robot arms move the wafer holding trays to the front of the station to a position optimally located for easy and effortless loading and unloading. Modutek applies such ergonomic design principles to wet bench access for increased safety of operators and technicians working in semiconductor fabrication facilities and research labs.

Ergonomically Designed Upgrades and Customization

When a facility is upgraded or additional equipment is retrofitted, standard ergonomic designs may not meet the needs of the completed installation. Equipment that fully satisfies ergonomic design principles on its own may be difficult to operate when placed in specific configurations. Modutek can apply the company’s experience with ergonomic design to customize installations, ensuring that a customer’s specific ergonomic requirements are met and that the installation as a whole is easy and safe for operators and technicians.

Modutek processing stations are available in a wide variety of configurations and the company works with the customer’s engineering team to custom design the best processing equipment for the particular application. The ergonomic engineering required to ensure easy and safe operation is integrated in these designs and guides the company when customizing their equipment for specialized needs.

How Technology Manufacturers Use Chemical Delivery Systems

How-Chemical-Delivery-Systems-are-Used-by-Technology-Manufacturers

Technology manufacturing requires the safe handling of chemicals as well as their delivery in accurate amounts. Corrosive chemicals are used for etching, cleaning and plating materials such as silicon chips, metal parts, solar system components and printed circuit boards. The chemicals have to be stored securely, delivered to the process in precise amounts, and neutralized before disposal. Automated chemical delivery systems reduce waste and operator error while allowing the supply of defined amounts of each chemical with a high degree of precision.

Technology manufacturers use these systems to supply chemicals to wet processing equipment. Acids are used to etch away layers of material on wafers of silicon, printed circuit boards or other substrates. Sections of the layers to be etched are covered in protective material and are not removed by the etching. In this way microscopic structures and conducting paths can be created. The requirements for chemical delivery systems depend on the application of the wet processing equipment and on the chemicals to be used.

The key to supplying effective chemical delivery systems is a flexible approach combined with the ability to develop systems customized to meet the needs of the manufacturer. Companies that manufacture silicon wafers have different requirements from those that manufacture micro-electro-mechanical systems, hard disk drives or solar cells. The cleaning and etching processes of different technology manufacturers use various chemicals and widely varying amounts and process control strategies. Their chemical delivery systems must be resistant to corrosion, be safe to operate, allow the storage of large amounts of chemicals and include flexible software to control distribution. An equipment supplier has to have a good understanding of the processes involved so that they can standardize the parts of the system that can remain the same while developing custom solutions to match the needs of each technology manufacturer.

Modutek specializes in designing and manufacturing systems that provide outstanding performance and reliability with the ability to be highly customizable. The systems incorporate user-friendly features that promote safe and cost-effective operation. In a typical custom application, water use, and the number of defective parts produced is reduced while consistency of results increases.

Modutek’s chemical delivery systems feature all Teflon fluid paths, double containment cabinet construction, leak detection and chemical level sensing. Double wall plumbing and system data logging are available. Chemical storage can be in large tote chemical containers or 55-gallon drums close to the wet process station. Manufacturers that use different chemicals can improve throughput because the Modutek’s systems are designed for quick chemical change.

The software that automates a chemical delivery system is a key factor in the system’s flexibility and Modutek can customize the software to meet the needs of the technology manufacturer. Typically a touch screen shows error messages on start-up and then displays a flow diagram showing the status of key components such as metering pumps, valves and level switches. Since these may be different for particular customized applications, the software must be easily adaptable. All the software for Modutek’s chemical delivery systems is written in house. This means that Modutek has the in house expertise and capability to make changes in the software as needed and can provide excellent technical support without having to rely on exterior sources.

The Modutek chemical delivery systems are suitable for any technology manufacturer application. They are specifically designed for easy customization and provide reliable, cost-effective operation. For additional information about Modutek’s Chemical Delivery Systems or related products call 866-803-1533 or email [email protected]

Modutek’s DR Series Quick Dump Rinser

Modutek Quick Drump Rinser DR Series

Modutek’s DR Series Quick Dump Rinser

Throughout wafer manufacturing, few steps are as critical as the D.I. (deionized water) rinse cycle. In most cases, your product is exposed to more D.I. water than any other process fluid. For this reason, a truly effective rinsing system can contribute dramatically to the reduction of particles and defect densities. A considerable amount of time has been given to help you make this transaction into our DR series quick dump rinser easy and affordable. Whether it’s upgrading your existing rinsing line or installing new wet process station we have the plan that will work best for you.

Our overall DR series Quick Dump Rinser is designed with two major features. One: Easy installation into new or used equipment and two: Low DI water consumption due to our rinse features.

Modutek's Quick Dump Rinser during the spray cycleSuperior and consistent rinsing is achieved by (1) strategically located D.I water spray nozzles, (2) bottom filling (3) N2 agitation and (4) bottom fill that creates a vortex agitation in the rinse tank (optional).

The interior volume of the DR Series Quick Dump Rinser was reduced to minimum size relative to the wafer cassette. This, along with a 360˚ overflow weir and rapid dump time ensures that all large and small contaminants are quickly removed from the surface of the wafer and surrounding areas, thereby preventing recontamination of the wafer.

Modutek C15sa Rinser Controller is used in conjunction with the Quick Dump RinserModutek’s C15sa Rinser Controller is specifically designed for use with the DR Series Quick Dump Rinser wafer rinse system and provides a high degree of process flexibility. The user has the ability to program dump cycle, fill cycles, start cascade and spray delay. In addition, our C15sa controller has the ability to be programmed for resistivity and incorporates an access code which prevents tampering with the program.

In order to rinse to resistivity, the DR Series is used in conjunction with the Modutek Resistivity Monitor RM30a (optional feature). The RM30a has the ability to monitor resistivity and temperature inside the DR series rinser as well as incoming water into the wet bench. Once resistivity setting is reached inside the Quick Dump Rinser the rinse cycle discontinues at the next full level. This results in a process specific rinse, ensuring that a minimal amount of DI water is used.

Modutek Quick Dump Rinser during full rinse cycleIn addition to all of these features Modutek’s Quick Dump Rinser is designed for new or used wet bench installations. With this design you can easily upgrade your old rinser and not incur the cost of a new wet bench. The water savings and the increased throughput will help cover the cost of the overall upgrade.
