In a semiconductor device producing method according to one embodiment, an insulating film containing silicon is formed on a semiconductor substrate, a resist is deposited on the insulating film, the resist is patterned into a predetermined pattern, and the insulating film is processed by a dry etching treatment in which gas containing C, F, Br, H, and O is used with the resist having the predetermined pattern as a mask. A deposited film in which C and Br are coupled is produced on the resist.
