ALKA-TEX .2+
Additive to improve alkaline texturing of monocrystalline Si-Wafers - new formula
overview

Situation

The narrow process window of the standard alkaline texturing process with KOH and IPA often leads to poor texture and is very difficult to control.
ALKA-TEX .+2, is a solution to improve texture quality and to broaden the process window.
