Wafer Cleaning Process -Modutek

RCA Clean. The RCA clean process was originally developed by RCA Corporation and is a cleaning method to remove organic residue from silicon wafers. The cleaning solution is made up of 5 parts water, 1 part 30% hydrogen peroxide, and 1 part 27% ammonium hydroxide. It is an effective way to remove organic contaminants and leaves a thin layer of oxidized silicon on the surface of the wafer.
