发明名称 Method of grinding wafer
摘要 A method of grinding a wafer, including: a wafer holding step for holding a wafer on a conical holding surface of a chuck table having the holding surface; a rough grinding step for performing rough grinding of the wafer held on the holding surface of the chuck table by positioning a grinding surface of a rough grinding wheel at a predetermined inclination angle relative to the holding surface of said chuck table, and rotating the rough grinding wheel; and a finish grinding step for performing finish grinding of the wafer by positioning a grinding surface of a finish grinding wheel in parallel to the holding surface of the chuck table, and rotating the finish grinding wheel in a grinding region of the grinding wheel in a direction toward the vertex of the contact angle between the grinding surface of the finish grinding wheel and the surface to be ground of the wafer.
