How to Order a Wet Bench for Your Specific Process Requirements
Wet processing used in semiconductor manufacturing includes many complicated process steps which need to be taken into account when ordering new wet bench equipment. When selecting a supplier, experience and capabilities have to be evaluated. Physical requirements such as space and output volume are essential. The degree of automation required also plays a significant role. […]
Why Stainless-Steel Stations Are Needed for Solvent Processing
During silicon wafer fabrication, BEOL (Back End of Line) processes may require solvent-based stations to ensure compatibility with semiconductor manufacturing steps. FEOL (Front End of Line) acid-based chemistry may not be suitable for BEOL finishing. Instead, stainless-steel stations with solvents such as acetone, IPA (Isopropyl Alcohol) or EDP (Ethylenediamine Pyrocatechol) complete wafer etching, stripping, and […]
Reasons to Use a Wet Bench Manufacturer with In-House Expertise
When dealing with third-party distributors who offer wet bench stations built by someone else, customers often pay more and get less. A wet bench manufacturer that designs and builds its own wet bench equipment in-house develops the expertise and capabilities needed to satisfy customer requirements. The manufacturer can respond directly to customer requests and design […]
Why Ergonomics and Safety Are Important in Wet Bench Station Design
Because semiconductor manufacturing with wet bench technology uses dangerous chemicals in many of the process steps, ergonomic design helps keep employees safe. Toxic and corrosive chemicals such as hydrochloric acid are used to clean, etch and strip silicon wafers in wet process stations. Ergonomics helps ensure that operators don’t have to strain or overextend themselves […]
How Automated Wafer Fabrication Equipment Optimizes Process Control
Fully or semi-automated silicon wafer fabrication equipment can reduce errors and improve repeatability in wafer processing while at the same time increasing flexibility. Automatic controls let operators change process parameters if required for different processes or for process optimization. Once a process runs in an optimized fashion, automated controls allow operators to make sure that […]
Important Things to Know Before Buying a Wet Bench Station
There are a number of process and production requirements that need to be considered before buying a wet bench station. In addition to knowing which process chemicals are needed, you also need to decide on the degree of automation and whether any customization is needed for your station. If your application requires the use of […]
How Stainless-Steel Stations Provide Safe Solvent Processing
Solvents used in semiconductor manufacturing can remove oils and organic contaminants from silicon wafers in preparation for further processing steps. Acetone, isopropyl alcohol (IPA) and ethylene diproxitol (EDP) are solvents commonly used to clean wafers, remove photoresists, and in pattern transfers for the creation of microscopic structures on the wafer. The solvents are inflammable and […]
How Process Controls Are Improved with Automated Wet Bench Equipment
When semiconductor manufacturing is automated, tight process control can improve overall facility performance. An optimized manufacturing process can reduce consumption of consumables and production results are more uniform. Once a batch has run successfully, an automated process ensures that it will run the same way for subsequent batches. With good design, automation reduces silicon wafer […]
Solvent Processing Using Stainless Steel Stations
Manufacturing processes using volatile solvents have to be specially designed to minimize the risk of explosions or fire. Solvents such as acetone or alcohol are used to clean parts, dissolve materials and extract substances. Modutek’s stainless steel stations meet strict safety regulations that reduce the risk of ignition of the solvents or their vapors and […]
5 Important Things to Know Before Buying a Wet Bench Station
Wet bench semiconductor manufacturing has many variations and applications often have unique features. Before buying a wet bench station, there are several main things to look at before deciding what equipment is best suited for a specific manufacturing task. Options include the type of station, how it operates, how it receives its chemicals and what […]
