Patent ID: 10971351

Abstract:
Example features relate to a method of polishing a chamfered wafer surface, the method including beveling a wafer to generate the chamfered wafer surface, the chamfered wafer surface being inclined with respect to a main wafer surface by an angle θ; and polishing the chamfered wafer surface with a polishing pad, a polishing surface of the polishing pad being inclined with respect to the chamfered wafer surface by an angle α; wherein the angle α is equal to or smaller than the angle θ. Example features relate to a system for polishing the chamfered surface, the system including a polishing pad mounting jig configured to polish the chamfered surface, an angle θ being defined between the chamfered surface and the main surface; and a polishing pad in contact with the chamfered surface at an angle α during polishing; wherein the angle α is smaller than the angle θ.
