Method of polishing a semiconductor wafer

摘要

A modified process for chemical/mechanical polishing semiconductor wafers is provided. The process includes polishing a surface of the wafer, contacting the polished surface of the wafer with a surfactant, and drying the surface of the disengaged wafer for a sufficient period of time before contacting the surface of the wafer with a rinse media or subsequent process liquid. The process reduces defects, including etching stains, on the polished surface of the wafer.
