Abstract
A grinder designed to provide an automatic grinding operation for the manufacture of a semiconductor device wafer. The grinder includes a base, a rotatable index table mounted to the base, and a grinding wheel assembly including a grinding wheel for grinding a flat surface on the wafer. The index table includes a wafer holder for receiving and holding the wafer and a dressing element for dressing the grinding wheel. The index table is selectively rotatable between a grinding position where the wafer is ground by the grinding wheel and a dressing position where the grinding wheel is dressed by the dressing element.
