Grinding; Lapping (1 or 2 steps) Polish and Chemical-Mechanical Polishing (CMP) Silicon Carbide Wafer Grinding. The EVG-250/300 series Vertical Grinding Machine combined with Engis MAD Grinding Wheels can achieve a superior surface finish on silicon carbide wafers to reduce or even eliminate loose abrasive lapping steps.

The machine picks up the wafer from its backside (untaped side) with a robotic arm, which positions the wafer for backgrinding. The backgrinding process is automatically accomplished by a grinding wheel, following a precise set of parameters to ensure proper backgrinding.

The wafer grinding machine uses a centrally located robot to move a wafer from an input station to a measuring station. Thereafter, the wafer is moved into a grind station and a wash station sequentially. The robot is able to move a wafer from the wash station to either the measuring station for after-grinding measurements or directly to an output station.

In this paper, wafer shape is defined as the shape of the wafer front surface when the wafer back surface is assumed to be flat. Fig. 3, Fig. 4 show two ground wafers, one with convex shape and the other concave shape. These wafers were ground on a Strasbaugh wafer grinder (Model 7AF, Strasbaugh, Inc., San Luis Obispo, CA) and measured on a flatness …
