Semiconductor device manufacturing method, semiconductor device manufacturing apparatus and semiconductor device

摘要

A method of manufacturing a semiconductor device, which comprises a step of forming an oxide film by oxidizing a surface of semiconductor layer in an atmosphere containing an oxygen-activated species at a temperature of over 550° C. A method of manufacturing a semiconductor device, which comprises the steps of forming an oxide film by oxidizing a surface of semiconductor in an atmosphere containing an oxygen-activated species, and removing the oxide film so as to expose a surface of the semiconductor. A method of manufacturing a semiconductor device which comprises a step of feeding an oxidizing source gas comprising as a main component oxygen atomic radicals of singlet state in an excited state to a silicon layer thereby to oxidize a surface of the silicon layer, thus forming a silicon oxide film.
