ProTEK(TM) Temporary Etch Protective Coatings


July 11, 2006 - Rolla, Missouri, USA. Brewer Science is pleased to announce the development of a new temporary protective coating system for basic etchants, which offer customers an alternative to their current wet-etch process materials. ProTEK(TM) etch protective coatings are spin-applied polymeric coatings designed to give maximum protection, durability, and longevity against harsh etchants during deep silicon wet-etching processes. Brewer Science's ProTEK(TM) coatings are capable of withstanding the adhesion challenges brought on by a variety of substrates including nitride, oxide, metals, glass, and various other materials. These coatings are compatible with a variety of semiconductor materials and are able to withstand and survive the etch process without decomposing or lifting off of the substrate. ProTEK(TM) coatings are easily removed after the etch process with ProTEK(TM) Remover or by an oxygen plasma process.

Typical applications that have been found to benefit from the unique properties of ProTEK(TM) temporary etch protective coatings include:
o Front-side protection during backside v-groove etch process
o Front-side protection during wafer-thinning process.
