Abstract

A method of manufacturing a semiconductor device includes forming a seed layer containing a predetermined element on a substrate by performing a process a predetermined number of times, and supplying a second precursor containing the predetermined element and not containing the ligand to the substrate to form a film containing the predetermined element on the seed layer. The process includes alternately performing: supplying a first precursor to the substrate to form an adsorption layer of the first precursor, the first precursor containing the predetermined element and a ligand which is coordinated to the predetermined element and which contains at least one of carbon or nitrogen, and supplying a ligand desorption material to the substrate to desorb the ligand from the adsorption layer of the first precursor.
