Precision Grinding of Ultra-Thin Quartz Wafers

Wafer Grinding Once the vacuum chuck has been machined under controlled grinding conditions, the wafer can be mounted and ground. Since the wafer is very thin, its back surface conforms closely to the chuck surface. The front surface is then ground as flat as possible, again using real-time feed-back control and a ref-erence flat. •.
