发明名称 METHOD FOR POLISHING A SEMICONDUCTOR WAFER
摘要 A method of polishing a semiconductor wafer using a holding system including a lined cutout the size of the semiconductor wafer that is fixed to a carrier. The method includes holding the semiconductor wafer in the cutout through adhesion of a first side of the semiconductor wafer to a bearing surface in the cutout and polishing a second side of the held semiconductor wafer using a polishing pad that is fixed on a polishing plate while introducing a polishing agent between the second side of the semiconductor wafer and the polishing pad, the polishing pad including fixedly bonded abrasive materials. The carrier is guided during polishing such that a portion of the second side of the semiconductor wafer temporarily projects beyond a lateral edge of a surface of the polishing pad.
