Filed: 2006-07-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a concave processing method of wafer which eliminates the piling up of grinding waste between gradually formed annular reinforcing part and a grinding stone upon processing the wafer so as to be concave.  <P>SOLUTION: The wafer W is retained in the retaining surface of a chuck table formed so as to be conical with a slight inclination having a summit at the center of rotation. Then the grinding stone 4 is positioned in parallel to the matrix of the cone of the grinding stone 4 of a grinding wheel, one side half of the circumferential direction thereof is pushed and contacted to grind the rear surface of the wafer W, and the grinding wheel is turned into a direction that the bottom side thereof is rotated to the summit side to grind backside of the wafer W. Accordingly, the grinding waste existing between a gradually formed annular reinforcing unit and the grinding stone 4 is taken out smoothly, so that the waste is swept out in accordance with the rotation of the grinding stone 4 to prevent its pileup between the annular reinforcing unit and the grinding stone 4.  <P>COPYRIGHT: (C)2008,JPO&INPIT
