发明名称 Method for chemically grinding a semiconductor wafer on both sides
摘要 A semiconductor wafer processed on both sides simultaneously, the wafer lying in freely movable fashion in a cutout in one of a plurality of carriers that rotate by means of a rolling apparatus, and one thereby being moved on a cycloidal trajectory, the semiconductor wafer being processed in material-removing fashion between two rotating ring-shaped working disks, wherein each working disk comprises a working layer comprising abrasive material, and wherein an alkaline medium comprising no abrasive material is supplied during the processing.
