Abstract
An CMP process will be presented which is optimised for low layout sensitivity and good uniformity. The best results were obtained by using a stack of two polishing cloths, instead of a single cloth. This results in a better planarisation capability while improving the uniformity compared to a single hard polishing cloth. The feasibility of the novel CMP process was demonstrated on a 64k SRAM.
