Chemical Wet Processing Table Top Units

Modutek provides small table top units to support chemical wet processing at research labs and universities for proof of concept or prototyping. Using a typical semiconductor manufacturing line for this purpose is expensive and does not provide flexibility. The use of small table top units allows wet processing to be scaled back to reduce equipment size without losing required functionality. Modutek’s table top units support the most important silicon wet processing functions needed to produce small volumes semiconductor products quickly and efficiently.

Support For Most Chemical Wet Processes

Modutek’s table top chemical wet processing systems are compact, self-supporting units that consist of a Temperature Remote control box and either a Teflon® tank for acid processes or a stainless-steel tank for solvent processes. The tanks are available as ambient or temperature-controlled models and can be static baths or recirculating baths with a filter.

Modutek’s Table Top Units Support the following Chemical Wet Processes:

• KOH Etching
• Solvent Resist Strip
• Buffered Oxide Etch (BOE)
• Other Wet Processes Available
