Patent ID: 8529315

Claim:
A method of producing a semiconductor wafer comprising the following steps in the recited order: (a) simultaneous double-side material-removal processing a semiconductor wafer sliced from a single crystal by processing the semiconductor wafer between two rotating ring-shaped working disks, each working disk including first abrasives having an average grain size in a range of 5.0 to 20.0 μm; (b) treating both sides of the semiconductor wafer with an alkaline medium; (c) grinding a front side and a rear side of the semiconductor wafer, the grinding of each side including fixedly holding a first of the front and rear sides using a wafer holder and processing the other of the front and rear sides using a grinding tool, the grinding tool including second abrasives having an average grain size that is smaller than the average grain size of the first abrasives and having an average grain size being in a range of 1.0 to 10.0 μm; (d) polishing both sides of the semiconductor wafer using a polishing pad including third abrasives having an average grain size in a range of 0.1 to 1.0 μm; (e) polishing the front side of the semiconductor wafer using a stock removal polishing pad that is free of abrasives and a polishing agent containing fourth abrasives; and (f) chemical mechanical polishing the front side of the semiconductor wafer.
