Texturing and Etching

To increase the surface area of a solar cell or to create trenches in MEMS device, alkaline etching using KOH (potassium hydroxide) and KOH/IPA are commonly used. For solar processing, controlled sizes of pyramids and uniform process of mono-crystalline silicon are necessary for increased efficiency. Smooth surfaces for MEMS are required for functional devices.
