Abstract:
A method and apparatus for within-wafer profile localized tuning is disclosed. In one aspect, the method includes providing a wafer attached to a rotating vacuum stage front side up, the wafer including a surface film with an incoming film thickness profile, providing a pad attached to a rotating head front side down, the head configured to sweep along a path, computing a film thickness removal amount based upon the incoming film thickness profile, and removing at least a portion of the surface film of the wafer based on the computed film thickness removal amount via a plurality of steps.

Claim (Index 11):
The method of  claim 3 , further comprising:\n determining the polishing parameters based on models including removal curves which characterize the correlation between the amount of film thickness removed at any location on the wafer to the polishing parameters, wherein the polishing parameters include one or more of: the size of the head, a down-force, the scanning speed, the wafer rotation speed, the head self-rotation speed, and the slurry flow-rate.
