A method for improving a photolithographic patterning process to avoid undeveloped photoresist contamination in a semiconductor manufacturing process including providing a semiconductor wafer having a process surface including a first anisotropically etched opening extending through a semiconductor wafer thickness portion including an underlying dielectric insulating layer; blanket depositing a polymeric resinous layer over the semiconductor wafer process surface to include filling the first anisotropically etched opening; curing the polymeric resinous layer by exposing the polymeric resinous layer to at least one of thermal or photonic energy to initiate polymer cross linking; chemically mechanically polishing (CMP) the polymeric resinous layer to substantially remove the polymeric resinous layer thickness above the process surface; and, forming a photolithographically patterned photoresist layer over the process surface for forming a second anisotropically etched opening overlying and encompassing the first anisotropically etched opening.

Method for avoiding photoresist resist residue on semioconductor feature sidewalls

A method and apparatus for implementing the method for preventing or reducing corrosion of copper containing features included in a semiconductor wafer in a chemical mechanical polishing (CMP) process the method providing at least one semiconductor wafer polishing surface including copper filled anisotropically etched features; polishing the at least one semiconductor wafer polishing surface according to a CMP process having a polishing pad surface contacting the at least one it semiconductor wafer polishing surface at least a portion of the polishing pad in electrically conductive communication with a conductive polishing platen; and, providing at least one electrically conductive pathway from the conductive polishing platen.
