Title: Specular polishing method for semiconductor wafer
Inventor: AKIYAMA HIROKI
IPC: B24B37/005
Filed: 1987-04-23
Abstract: PURPOSE:To prevent the generation of an oxide film after polishing by using a water polishing method after finishing a polishing process by means of a polishing liquid, and feeding an alkali salt water solution for assisting machining performance immediately before starting the operation. CONSTITUTION:At the time of polishing, e.g. a GaAs semiconductor wafer, the wafer is stuck to a sticking plate made of ceramic and installed on a rotary surface plate, and pressed against a polishing cloth of a suede type polishing cloth using a polishing liquid of a sodium hypochlorite group corrosive liquid, to be polished into a specular face at a depth of approx. 30mum. After the end of this polishing, the supply of the polishing liquid is stopped and, with a polishing pressure kept about 50g/cm<2>, a 5% sodium carbonate solution approx. 300cc in total is fed for approx. 3sec at a rate of approx. 100cc/sec and, after that, water polishing is carried out for approx. 15sec with a quantity of water at a rate of 3l/min. Thus, by using both the washing by means of an alkali salt water solution and water polishing at the time of specular polishing, a stable specular wafer can be obtained without causing a scratch or a buff mark, etc.
