摘要： A method for forming a nitride film is provided. The method includes preparing a substrate to be processed, the substrate having a first base film formed of a material having a relatively long incubation time and a second base film formed of a material having a relatively short incubation time with respect to a nitride film, forming a nitride film on the substrate by means of ALD or CVD using a raw material gas and a nitriding gas while heating the substrate to a predetermined temperature, and etching nitride on the first base film to be removed by supplying an etching gas to thereby expose a film surface of the first base film, wherein the forming the nitride film and the etching the nitride are repeatedly performed a predetermined number of times to selectively form the nitride film on the second base film.
