Organics

Organic contaminants are known to affect pyramid size during wafer texturing process. Organics from wafer handling and transport plastic containers, process operators, ambient air, forklifts and adhesive are commons contaminants found in cell manufacturing. It is imperative to understand the source of organics and develop cleaning chemistries for organics removal prior to texturing process.
