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 1):
A method for thickness profile tuning, comprising:\n providing a rotating vacuum stage configured to hold a wafer, the wafer comprising an upwardly facing surface film with an incoming film thickness profile; providing a pad attached to a rotating head, the pad comprising a downwardly facing front side surface, the head configured to sweep along a path, a surface area of the head being less than a surface area of the wafer; removing at least a portion of the surface film of the wafer via a plurality of steps, each of the steps comprising:\n bringing the surface film of the wafer and the front side surface of the pad into contact with each other, and \n sweeping the head along the path; and \n adjusting one or more parameters for each of the removal steps to affect an amount of film thickness removed, wherein the one or more parameters are adjusted based on the incoming film thickness profile and a criteria for the within-wafer-uniformity of the wafer.
