wafer, and an overall wafer fl atness measurement. With the wafer sizes of the time, it was desirable to support the wafer in a simple manner that was easily reproducible, so the three-point mount was perfect. It is a kinematic support, so any three-point support should result in the same defl ections.

Understanding simultaneous double-disk grinding: operation

·

Simultaneous double-disk grinding is a novel and powerful technology for silicon wafer planarization as required for the latest and upcoming future microelectronic device design rules. DDG uses two opposite grinding wheels, which simultaneously flatten both sides of the free-floating wafer between them in a single process step.
