摘要： A polishing apparatus includes a detachable light weight cloth cartridge which shows little deformation under uneven loading during a polishing operation. Either mechanical or non-mechanical fixation of the cloth cartridge to a turntable is achieved. Mechanical fixation involves attaching the cloth cartridge to the turntable at peripheral and center sections of the cloth cartridge. Non-mechanical fixation involves attaching the cloth cartridge to the turntable by a vacuum arrangement. The assembly of the cloth cartridge and the turntable not only produces excellent flatness on polished semiconductor wafers by maintaining a level polishing surface, but also improves the production yield by preventing breakage of wafers during the polishing process.

摘要： A semiconductor cleaning method includes scrubbing a semiconductor wafer using a cleaning member made primarily of polyurethane and having micropores in a surface contacting the semiconductor wafer. The micropores have an average diameter ranging from 10 to 200 .mu.m. The cleaning member may be made of either polyurethane foam or non-woven fabric composed of fibers bound together by urethane resin. By this scrubbing step, particles that are strongly attached to the surface of a substrate such as the semiconductor wafer can easily be removed. During cleaning of the substrate, surface irregularities and crystalline protrusions on the surface of a substrate such as a semiconductor wafer can be scraped off to adjust the surface roughness of the semiconductor wafer to a desired degree for making the semiconductor wafer surface flat.
