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 Teflon Tanks Improve the KOH Etching Process
Etching silicon wafers with potassium hydroxide (KOH) is a popular process for semiconductor manufacturing because it is relatively safe compared to other etching methods and because it features good control of the etch rate. When carried out in Teflon tanks, contamination is reduced and the etch rate can be controlled. A key factor for successful […]
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 […]
How Chemical Carts Provide Safe Handling and Disposal of Chemicals
Chemical handling equipment is an important part of a semiconductor manufacturing operation because the aggressive chemicals used in etching and cleaning semiconductor wafers have to be stored, delivered to the process, and disposed of safely.
