After the wafers have been sliced, the lapping process begins. Lapping the wafer removes saw marks and surface defects from the front and backside of the wafer. It also thins the wafer and helps to relieve stress accumulated in the wafer from the slicing process. After lapping the silicon wafers, they go through an etching and cleaning process.
