Patent ID: 10099339

Abstract:
A chemical mechanical polishing apparatus includes a polishing zone having a wafer entrance and a wafer exit, first wafer platform, polishing module, slurry injection module, polishing cleaning module, and film-thickness measuring module. The first wafer platform includes a wafer loading region, and is able to move from the wafer entrance to the wafer exit along a first direction. The polishing module is located in the polishing zone, including a polishing belt extended along a second direction perpendicular to the first direction and is able to move along the second direction. The slurry injection module is configured for injecting slurry towards a wafer to-be-polished by the polishing module. The polishing cleaning module is located on one side of the polishing module along the first direction for cleaning the wafer. The film-thickness measuring module is located on another side of the polishing module along the first direction for measuring the thickness of the wafer.
