Silicon Wafer an overview ScienceDirect Topics

Silicon wafers after cutting have sharp edges, and they chip easily. The wafer edge is shaped to remove sharp, brittle edges; rounded edges minimize the risk for slipping, too. The 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 made.
