Claim Text:
1. A method of manufacturing a semiconductor device, comprising forming a laminated film where a first film and a second film are laminated on a substrate by performing a cycle a predetermined number of times under a condition where a borazine ring structure in a fourth process gas is maintained, the cycle comprising: (a) forming a film free of the borazine ring structure and including boron and nitrogen or a film free of the borazine ring structure and including boron, carbon and nitrogen as the first film by performing a first set a predetermined number of times, wherein the first set comprises: supplying a first process gas free of the borazine ring structure and including boron to the substrate and supplying a second process gas including nitrogen or including nitrogen and carbon to the substrate; and (b) forming a film having the borazine ring structure and including boron and nitrogen or a film having the borazine ring structure and including boron, carbon and nitrogen as the second film by performing a second set a predetermined number of times, wherein the second set comprises: supplying a third process gas to the substrate and supplying the fourth process gas having the borazine ring structure and an organic ligand to the substrate.
