Abstract
A film forming method for forming a thin film including boron, nitrogen, silicon, and carbon on a surface of a processing target by supplying a boron containing gas, a nitriding gas, a silane-based gas, and a hydrocarbon gas in a processing container in which the processing target is accommodated to be vacuum sucked includes: a first process which forms a BN film by performing a cycle of alternately and intermittently supplying the boron-containing gas and the nitriding gas once or more; and a second process which forms a SiCN film by performing a cycle of intermittently supplying the silane-based gas, the hydrocarbon gas, and the nitriding gas once or more. Accordingly, the thin film including boron, nitrogen, silicon, and carbon with a low-k dielectric constant, an improved wet-etching resistance, and a reduced leak current can be formed.
