Claim Text:
1. A method of manufacturing a semiconductor device, comprising: forming a film consisting of a predetermined element on a substrate by performing a cycle a predetermined number of times, the cycle including: supplying a first precursor containing the predetermined element and a halogen group to the substrate; supplying a second precursor containing the predetermined element and an amino group to the substrate; and supplying a reducing agent not containing halogen, nitrogen and carbon to the substrate, wherein the act of forming the film consisting of the predetermined element includes: forming a first layer containing the predetermined element on the substrate by performing the act of supplying the first precursor and the act of supplying the second precursor, wherein the halogen group of the first precursor and the amino group of the second precursor react to form a reaction product to be removed from the first layer; and forming a second layer consisting of the predetermined element on the substrate by supplying the reducing agent to modify the first layer.
