Patent ID: 6863590

Claim:
A wafer planarization apparatus, comprising: a processing part which holds a wafer through a protective sheet adhering to a first surface of the wafer and processes a second surface of the wafer; an inspecting device which inspects the wafer having been processed by the processing part; a frame adhering part which adheres a frame through a sheet to the second surface of the wafer having been inspected by the inspecting device; a peeling part which peels the protective sheet from the wafer to which the frame has been adhered; and a transporting device which transports the wafer between the processing part, the inspecting device, the frame adhering part, and the peeling part; wherein the inspecting device is located within the planarization apparatus between the processing part and the frame adhering part, wherein the inspecting device comprises a thickness measuring device which measures a thickness of the wafer, and the inspecting device rejects the wafer of which thickness is thicker than a predetermined thickness.
