Silicon Wafer

Silicon wafers after cutting have sharp edges, and they chip easily. Wafer edge is shaped to remove sharp, brittle edges; rounded edge minimizes risk for slipping, too. Edge shaping operation makes the wafer perfectly round (off-cut wafers are oval shaped after slicing), the diameter is adjusted, and orientation flat(s) or notch is dimensioned or

Polished optical grade silicon, high resistivity

If required, after downsizing the wafer the orientation flat or notch can be re-cut into the re-sized wafer. Super polished surface finishes 7-10 Angstroms are available, and Silicon can be thinned to as thin as 20-25um thick (in 1cm square size). Silicon wafers can

Silicon Wafer Manufacturing Process

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.
