Web lift system for chemical mechanical planarization
First Claim
1. A method for moving a web of polishing material comprising the steps of:
- supporting a portion of the web of polishing material on a platen between a first member and a second member; and
moving at least one of the first or the second members against an underside of the web to an extended position relative the platen that places the portion of the web in a spaced-apart relation with the platen.

Abstract
Generally, a method and system for lifting a web of polishing material is provided. In one embodiment, the system includes a platen that has a first lift member disposed adjacent to a first side and a second lift member disposed adjacent to a second side. The platen is adapted to support the web of polishing media that is disposed between the first and the second lift members. A method includes supporting a web of polishing media on a platen between a first lift member and a second lift member and moving at least the first lift member or the second lift member to an extended position relative the platen that places the web in a spaced-apart relation with the platen.
