Within wafer non-uniformity (WIWNU), which significantly affects the yield of chip products, is mainly caused by non-uniform chemical mechanical polishing (CMP) at the wafer's edge. This study investigates the origins of the non-uniformity and presents a process that uses an edge profile control rin...
