Modutek’s Wet Bench Design Process

Modutek's Wet Bench Design ProcessIn an effort to meet the highest customer expectations, Modutek has developed a wet bench design process that emphasizes collaboration with customers and dedicates the full resources of the company to identifying and satisfying customer requirements. Key features of the process are an emphasis on quality, an orientation toward partnering with the customer, a project-based account management structure and the use of the latest design tools. With this approach to wet bench equipment design, Modutek intends to ensure that the company meets the highest levels of customer satisfaction.

Design Goals

While meeting and exceeding customer expectations is the overall goal, Modutek emphasizes wet bench process results as well. A high-quality wet bench must be designed for high throughput with a long service life and a low level of downtime. High product quality requires a high level of extremely precise control. Based on these essential features, Modutek starts a conversation with the customer to identify his particular needs.

Partnership Design Program

To begin with the process, Modutek technical personnel gather all the details of their customer’s application. Specifications, data, descriptions and parameters are collected to allow Modutek to understand the customer’s business. The company can then develop the criteria for a successful design together with the customer. The business needs for wet benches, wet process tools, chemical delivery systems or custom semiconductor equipment are explored in detail. At the end of this process the requirements for a successful design are clear.

Design Tools

Once the design requirements have been identified together with the customer, Modutek uses advanced tools to help with design and modeling. Three dimensional design tools ensure precision and the accuracy of the models. Such 3-D designs are created for all wet process and chemical delivery systems, to show the positions of all components and to form the basis for a detailed design review. Once approved, the same material is used to create complete documentation, including post installation maintenance manuals. Using a single set of designs to generate all the documentation ensures that performance is always consistent, even when many units are produced.

Project Management

To execute the production as specified in the designs, Modutek focuses on managing accounts as projects. For each order, the company assigns a dedicated project manager to lead the work. He coordinates with the customer to make sure the design, engineering, manufacturing and integration remain on track. Delivery and installation at the end of the project are handled the same way. The project manager is responsible for ensuring basic technical requirements are met and the customer’s input is respected, leading to a high quality design that meets the customer’s needs.

Factors for a Successful Design Process

Four factors allow Modutek to offer a collaborative design process that gives superior results. First, the company has the experience and broad line of wet bench equipment to respond to a wide variety of customer requirements. Secondly, the company designs and builds all process, etching or cleaning components of its wafer fabrication equipment in house. Thirdly, all automation design is carried out in house, with Modutek engineers designing and writing the software. Lastly, Modutek’s SolidWorks Simulation Professional and SolidWorks Flow Simulation tools help design the system to get the end results specified. All of these factors must be in place for the successful implementation of the type of design process offered by Modutek, and the company works hard to ensure these prerequisites are retained in order to deliver the superior customer-centric service they make possible.

Using the KOH Etching Process with Modutek’s Teflon Tanks

Potassium hydroxide-KOH etching is an efficient chemical process that allows for precise impressions to be made within a body of silicon. The process uses DI (deionized) water in combination with heavy alkalinity (pH levels greater than 12); the solution is then thermally adjusted for the appropriate degree of etching needed. This process allows for greater precision than other forms of etching when it comes to manufacturing silicon wafers.

What Are the Benefits of Using KOH Etching?

The precision KOH etching grants is very beneficial to the product’s outcome. Due to its chemical composure and procedural approach, dry etching is more apt to create physical flaws; it also can make for a more hazardous environment, as it risks the exposure of toxic — even explosive — chemicals.

KOH etching, on the other hand, is almost entirely aquatic. The liquids for the etching process are contained within Modutek’s own Teflon Tanks, meaning that exposure to hazardous chemicals is drastically reduced to create a safe environment for manufacturing. The structuring behind the process also means that it can easily be set up for repeat manufacturing; the resources required for the etching are more stable and affordable, meaning that clients can duplicate their etchings at a much more feasible rate.

How Do Teflon Tanks Bolster the KOH Etching Process?

Modutek’s Teflon Tanks are designed with the foresight to emphasize the maximum potential KOH etching can provide. Furthermore, each Teflon Tank is fashioned to cater to the specific needs of the client, regardless of unorthodoxy. In unison with wet bench equipment, these Teflon Tanks greatly reduce the impurities other methods of etching may establish, providing you with a more reliable and consistent output every time.

The Teflon Tanks can be thermally adjusted to operate between 30 — 100º C (86 — 212º F), and on average can heat up at a rate of 2 — 3º C per minute, though smaller or larger tanks may have varying thermal increase rates. Thermal output can be mustered either from inline Teflon heating, or from submersion within an overflow bank for each type of Teflon Tank. Each tank is also fitted with cooling coils that can quickly reduce the solution’s temperature.

There are two types of Teflon Tanks that support KOH etching: Temperature Controlled Re-circulating Baths (TFa Series), and Temperature Controlled Static Baths (TI Series). These two series of Teflon Tanks are designed with overlapping covers to minimize the loss of water during the etching process; they also boast the ability to eliminate concentration deficiency.

Because Modutek designs their Teflon Tanks with the client’s specifications in mind, the customization each tank receives is advantageous to the desired end result. Dual heating methods produce a quick, balanced aid to water-based etching. Drains and valves can be installed into the tanks for safe and easy clean-up. Remote timers, controllers, or even a data interface can be equipped to make a simple process even simpler.

When compared to other forms of etching (whether wet or dry), Modutek’s support of KOH etching produces more precise and affordable results in a safer and more expeditious work environment. Teflon Tanks can be produced individually or en masse depending on the output the client is in need of. Each tank can also be fitted with a number of practical options that can improve the etching process dramatically.

No client should work with an environment or product that diminishes the quality of their manufacturing process; customization leads the way for an innovative and effective product. Modutek’s support of KOH etching in their catalytic Teflon Tanks will provide exceptional results for clients that use this process.

Benefits of Using Quick Dump Rinsers for Silicon Wet Etching

Benefits for Using Quick Dump Rinsers for Silicon Wet EtchingQuick Dump Rinsers are used during the rinse cycle in the silicon wet etching process. The deionized water (DI) rinse cycle is a vital step in your wafer manufacturing process. In fact, DI water probably contacts your product more than any process solution. This makes an efficient rinsing system invaluable to particle and defect density reduction. Fortunately, Modutek Corporation offers the DR Series Quick Dump Rinser for thorough, economical cleaning. Their experienced specialists can upgrade existing rinsing modules and install fresh-from-the-factory wet bench process stations to suit your specific needs.

Features and Functionality

For optimal operations, Modutek includes two defining features into each DR Series Quick Dump Rinser: limited DI water use and easy installation into new or used stations. These properties complement complete rinsing enhanced by:

  • Ergonomic DI water spray nozzles
  • N2 agitation
  • Bottom filling
  • Optional rinse tank vortex agitation
  • Dual overhead spray manifolds

In addition, Modutek has reduced the interior volume of their Rinsers to suit the size of your wafer cassettes. This design expedites dump time through a large, machined dump door and utilizes a surrounding overflow weir to remove all contaminates while preventing recontamination on wafer surfaces.

A Compatible Controller 

Complete your DR Series Quick Dump Rinser with Modutek’s compatible C15sa Rinser Controller. Designed specifically for the wafer rinse module, the controller provides convenience with a high degree of adjustability. Engineers program the fill and dump cycles and initiate cascade and spray delay at the click of a button. Safety features include access code-protected resistivity to prevent unwanted changes to the program.

A Monitored Rinse

Use the Modutek Resistivity Monitor RM30a with the DR Series wafer rinse system for a meticulous oversight of your cleaning process. Along with measuring resistivity, the optional RM30a monitors in flowing water into your wet bench station and internal temperatures of the DR Series rinse system. For minimal DI water consumption, rinse cycles automatically finish after reaching the resistivity setting. This ensures a fully adjustable, conservative rinse.

Whether you desire to upgrade your old rinse system or customize a new wet bench, the Modutek DR Series Quick Dump Rinser installs seamlessly. Even if you choose the latter, Modutek’s rinse system design ensures you save money on water costs throughout years of operation. Also don’t forget to consider increased throughput on all of your manufacturing projects.

How to Develop a Requirements List When Buying Wet Bench Equipment

How-to-Develop-a-Requirements-List-When-Buying-Wet-Bench-EquipmentChoosing the right wet bench equipment is a huge challenge for a manufacturing company or research facility. The equipment represents a major investment and you don’t want to spend a lot of money to find out the system doesn’t meet all your requirements. Secondly, the complex nature of wet bench equipment often makes the selection process even more difficult. In many cases, wet benches are designed to handle specific processes for wafer manufacturing. You need to insure that the equipment can support all your chemical processing and through put requirements.

That’s why you need to carefully evaluate your needs as you prepare to buy a wet bench. Below are 7 things you need to consider when buying wet bench equipment.

  • Wafer or substrate size

Before you even think about the equipment you want to buy, consider what wafer or substrate sizes it can handle. Different applications utilize different processes and wafer sizes, which applications do you need? Fortunately Modutek’s wet bench stations can handle all manufacturing process and wafer sizes up to 12″, whichever wet station you choose; manual, automated, or semi-automated.

  • Cassettes per bath

How many wafer cassettes per bath can the wet bench equipment hold? Some equipment can hold 2 wafer cassettes per bath; others can only hold one cassette per bath. An even more important feature is how the wafers are moved between baths. In some equipment, the movement is manual while in others it is automatic.

  • Is FM approval required?

FM Global Standards form the basis approval assessment of manufacturing equipment used in the semiconductor industry. It is a general understanding in the industry that equipment addressed as FM Standard are custom built rather than produced in mass. The manufacturer’s ability to produce consistently standard products is assessed on a regular basis during FM Approval’s product follow-up program.

  • Is CO2 fire system required?

Considering the fire risk posed by wet bench processes when solvents are used, most manufacturers fit their equipment with fire extinguisher systems. A common trend is to fit the equipment with CO2 fire suppression systems (Acid benches do not require CO2). See if the fire extinguisher suppresses fires without leaving behind foam, water, or dry chemical that may damage sensitive equipment parts.

  • Is a third party electrical inspection needed?

SEMI S2, CE, and 3rd party tests are an excellent way to test your system for consistency and efficiency. Modutek uses SEMI S2, NFPA, and NEC as guidelines in manufacturing wet processing equipment and can also provide a quotation for inspection reports as requested. You’re guaranteed that all systems will pass 3rd party electrical inspections.

  • Wafer volume requirements per day/week

How many wafers do you expect to process per day/week? As most process engineers have discovered, Modutek’s dry-to-dry wet processing equipment eliminates the need to dry using a separate tool. Fitted with an MVD Series IPA Dryer, the equipment shortens overall manufacturing process allowing for greater yield per unit time.

  • Exhaust/chemical fume hood filtration requirements

Since hazardous fumes are produced in wet bench process, an exhaust mechanism is critical to all processes. Modutek provides a chemical fume hood that gives you a quick and low cost means to dispose of hazardous chemicals from the work station. Featuring white polypropylene construction for base and acid processes and stainless steel construction for solvent applications, the fume hoods are easy to install and set up, low cost, and meet or exceed all safety standards.

Summary

Remember that you always have the choice of manual, semi-automatic, and automatic wet bench stations. Other factors you may need to consider include: pump requirements, in-line heater needs, and station layout. For more information, contact Modutek on 866-803-1533 or 408-362-2000.
