Abstract
There is provided a technique that includes: forming a nitride film containing a predetermined element on a substrate in a process chamber by performing a cycle a predetermined number of times, the cycle including sequentially performing: (a) supplying a first precursor gas containing a molecular structure containing the predetermined element to the substrate with a pressure of the process chamber being set to a first pressure; (b) supplying a second precursor gas, which is different from the first precursor gas and contains a molecular structure containing the predetermined element and not containing a bond between atoms of the predetermined element, to the substrate with the pressure of the process chamber being set to a second pressure higher than the first pressure; and (c) supplying a nitriding agent to the substrate.
