Fast and precise surface measurement of back-grinding ...

The rotation axis of the grinding wheel is positioned off-axis to the rotation axis of the wafer (distance is the radius of the wafer). The chuck has a slightly conical shape which deforms the wafer with a very little tilt to ensure that the grinding wheel only contacts half of the wafer during the grinding process.

What is a Silicon Wafer? Silicon Valley Microelectronics

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.
