ABSTRACT:
Substrate processing methods involve forming an insulating film of amorphous carbon on a substrate by supplying acetylene gas and hydrogen gas with a volume ratio of 4:3 to 4:1, or alternatively, butyne gas, into a process vessel in which the substrate is accommodated. The methods further involve generating a plasma inside of the process vessel by emitting a microwave. The pressure inside of the process vessel is maintained to be 4.0 Pa or less and the substrate is maintained to be 200° C. or less while the insulating film is formed.
