Poly etch wet clean
WebDry photoresist ashing, stripping, and descum use oxygen plasma to generate radical oxygen species to chemically remove the photoresist layer on the silicon wafer. The byproducts of oxygen plasma ashing are not toxic. It’s more environmentally friendly than the wet etching process. Energetic electrons inside the plasma can break down oxygen ... http://www.erc.arizona.edu/education/mme%20course%20materials/MME%20Modules/Surface%20Prep%20Module/Wet%20Etching%20and%20Cleaning%20-%20Surface.ppt
