Abstract:
A localized chemical mechanical polishing (CMP) platform is provided. A table is configured to support a workpiece with a to-be-polished surface. A polishing pad is spaced from the table with a width less than about half that of the table. The polishing pad is configured to individually polish rough regions of hillocks or valleys on the to-be-polished surface. A slurry distribution system is configured to apply slurry to an interface between the polishing pad and the workpiece. A cleaning system is configured to clean the workpiece in situ on the table. A drying system is configured to dry the workpiece in situ on the table. A method for CMP with local profile control and a system with local profile control are also provided.
