Fine grinding of silicon wafers: designed experiments

The grinding force measured is the interaction force between the grinding wheel and the wafer in the direc-tion parallel to the spindle axis. It is also the direction perpendicular to the wafer surface. The maximum force during the entire grinding cycle is used for analysis. The monitor of the grinder displays the spindle motor current during ...
