Method for polishing semiconductor wafer edges

摘要

A system and method for polishing the edges of a plurality of semiconductor wafers rotates a stack of wafers against a polish one or more pads such that both the wafer edges and the sides of the edges are polished to a mirror finish. The polish pad has a series of grooves through which the wafer edges are passed to polish the sides of the wafer edges, or two pads are used, one with grooves and one without grooves.
