Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To reduce the breakage, chipping, etc., of a wafer by a method wherein specific quantities of two kinds of diamond particles which contain extra-fine particles and whose average particle diameters are different from each other are mixed and contained in a whetstone. SOLUTION: In the beveling process of a wafer 1, the circumferential edge of the wafer 1 is pressed against a rotating whetstone 2 such as a trapezoidal whetstone while the wafer 1 is made to rotate to bevel the edge. A beveling angle is about 22 ±5 deg.. A whetstone which contains 5-30wt.% of extra-fine diamond particles whose average particle diameter is 3-18μm and, further, contains 70-95wt.% of diamond particles whose average particle diameter is 5-30μm is used in the whetstone 2 for beveling.
