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 18):
The system of  claim 17 , wherein the one or more parameters comprise one or more of: a size of the head, a head scanning method, a head scanning path, a number of the zones into which the path is divided, starting and ending positions of the zones, a within-zone tuning strategy, polishing parameters, a scanning speed, a wafer rotation speed, a head self-rotation speed, and a slurry flow-rate, and wherein at least one of the parameters is different for two of the steps.
