Brewer Science ProTEK® B3 Alkaline-Resistant Coating
Categories: Other Engineering Material

Material Notes: 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. ProTEK® B materials offer protection from alkaline solutions such as KOH and TMAH for extended bath etches.
  • Protect delicate front-side circuitry during backside bulk micromachining
  • Increase yield by minimizing front-side damage caused by alkaline etch solution punch-through during wet etching
  • Improve throughput by reducing labor and process time associated with mechanical clamps and increasing the number of wafers per etch bath
The ProTEK® B3 Primer and ProTEK® B3 Protective Coating are applied separately. The film thickness can be varied through adjustment of spin speed. Suggested spin speeds are between 1000 rpm and 4000 rpm.
