Transition metal thin film forming method
摘要:
A semiconductor substrate is placed in a predetermined processing vessel, and oxygen gas activated by, e.g. conversion into a plasma is supplied onto an insulating film. The surfaces of an interlevel insulating film and insulating film are exposed to the activated oxygen gas. After that, a transition metal film, e.g. a ruthenium film, is formed by CVD.
