Abstract
Methods of oxidizing the surface of a photoresist material on a semiconductor substrate to alter the photoresist material surface to be substantially hydrophilic. Oxidation of the photoresist material surface substantially reduces or eliminates stiction between a planarizing pad and the photoresist material surface during chemical mechanical planarization. This oxidation of the photoresist material may be achieved by oxygen plasma etching or ashing, by immersing the semiconducter substrate in bath containing an oxidizing agent, or by the addition of an oxidizing agent to the chemical slurry used during planarization of the resist material.
