Analytical prediction for depth of subsurface damage in ...Silicon (100) wafers were adopted in the experiment, the diameter of the wafer is 200 mm. The initial thickness of the wafer is about 725 μm before grinding, and final thickness after grinding is 300 μm. The experiment was performed on a wafer grinding machine (CETC JB802). Resin bonded grinding wheel with mesh size of #320 was adopted.

Grinding wheel grit size Oct 03, 2015· Does the number given to conventional grinding wheels grit have an actual meaning. Say a 60 grit alum oxide. Does the 60 mean something. And where does diamond and CBN grit come into the equation? For example does a 60 grit diamond or CBN wheel exist, and if .
USB2 Method for directional grinding on backside ...A backside grinding apparatus removes semiconductor material from a surface of a semiconductor wafer. The wafer is mounted to a backing plate. The backside surface undergoes a first grinding operation in a rotational motion to remove excess semiconductor material. The semiconductor wafer is then aligned such that edges of the die are oriented along a reference line.
