Claim Text:
1. A method of manufacturing a semiconductor device, comprising: forming a film on a substrate, the film including a first element and a second element different from the first element, by performing a cycle a predetermined number of times, the cycle including: (a) forming a first layer that includes the first element by supplying a first gas that includes the first element to the substrate in a process vessel; and (b) forming a second layer that includes the first element and the second element by supplying a second gas that includes the second element to the substrate in the process vessel to modify the first layer, wherein pressure in the process vessel in one process of (a) and (b) is controlled to be higher than pressure in the process vessel in the one process when the film having a stoichiometric composition is formed, or pressure in the process vessel in the other process of (a) and (b) is controlled to be lower than pressure in the process vessel in the other process when the film having the stoichiometric composition is formed, so as to form the film having a composition where one of the first and second elements is excessive as compared with the other in terms of the stoichiometric composition, and wherein the first layer includes a discontinuous layer.
