APPARATUS AND METHOD FOR TARGET THICKNESS AND SURFACE PROFILE UNIFORMITY CONTROL OF MULTI-HEAD CHEMICAL MECHANICAL POLISHING PROCESS
Abstract:
An apparatus and method for providing target thickness and surface profile uniformity control of a multi-head chemical mechanical polishing (CMP) process is disclosed. An exemplary method includes providing at least two wafers; determining a surface profile of each of the at least two wafers; determining an operation mode for a chemical mechanical polishing (CMP) process based on the surface profiles of the at least two wafers; determining a CMP polishing recipe for each of the at least two wafers based on the operation mode; and performing the CMP process on the at least two wafers based on the determined CMP polishing recipes.
