Configuration for polishing disk-shaped objects

A polish head for Chemical Mechanical Polishing includes a backing film of silicone on a rigid support element, preferably, of amorphous ceramic. The silicone backing film is fabricated by molding, thereby enabling an appropriate cross-sectional shape for specific polishing needs. The head provides...

Beschreibung
Zusammenfassung:	A polish head for Chemical Mechanical Polishing includes a backing film of silicone on a rigid support element, preferably, of amorphous ceramic. The silicone backing film is fabricated by molding, thereby enabling an appropriate cross-sectional shape for specific polishing needs. The head provides a uniform polishing of a semiconductor wafer.
