ProTEK® PSB Coatings

ProTEK® PSB coating is a spin-on replacement for silicon nitride or silicon oxide wet etch masks

ProTEK® B3 Coatings

ProTEK® B3 coatings thin films are spin-applied polymeric coating systems that provide temporary wet-etch protection for CMOS MEMS circuitry during alkaline or acid etches.
