摘要:
A method of performing chemical mechanical polish (CMP) processes on a wafer includes providing the wafer; determining a thickness profile of a feature on a surface of the wafer; and, after the step of determining the thickness profile, performing a high-rate CMP process on the feature using a polish recipe to substantially achieve a within-wafer thickness uniformity of the feature. The polish recipe is determined based on the thickness profile.
