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 16):
A system for thickness profile tuning of a wafer, comprising:\n a rotating vacuum stage configured to hold a wafer, the wafer comprising an upwardly facing surface film with an incoming film thickness profile; a rotating head; a pad attached to the rotating head, the pad comprising a downwardly facing front side surface, the rotating head configured to sweep the pad along a path, a surface area of the head being less than a surface area of the wafer; a controller; and a computer-readable memory in communication with the controller and having stored thereon computer executable instructions to cause the controller to:\n remove 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 down surface of the pad into contact with each other, and \n sweeping the head along the path, and \n \n adjust one or more parameters for each of the removal steps to affect an amount of film thickness removed, \n wherein the one or more parameters are adjusted based on the incoming thickness profile and a criteria for the within-wafer-uniformity.
