Silicon Wafer Manufacturing Process - Silicon Valley ...

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.

US6306016B1 - Wafer notch polishing machine and method of ...

The notch polishing machine employs a plurality of polishing tapes which can be sequentially introduced into the notch of a wafer to polish both sides of the notch, i.e. the top and bottom surfaces. Each tape is pulled off a supply reel and passed into a mounting block sized to fit into the wafer notch. Each block is also mounted to be oscillated to effect a polishing action.
