Abstract

A retaining ring for use with electrochemical mechanical processing is described. The retaining ring has a generally annular body formed with a conductive portion and a non-conductive portion. The non-conductive portion contacts the substrate during polishing. The conductive portion is electrically biased during polishing to reduce the edge effect that tends to occur with conventional electrochemical mechanical processing systems.
