Method of manufacturing semiconductor device, substrate processing apparatus and recording medium
A method of manufacturing a semiconductor device includes forming an oxide film containing a metal element on a substrate by performing a cycle a predetermined number of times, the cycle including non-simultaneously performing: supplying a precursor containing a metal element and a halogen group to the substrate; and supplying an oxidant to the substrate. In the act of supplying the oxidant, a catalyst is supplied to the substrate together with the oxidant. In the act of supplying the precursor, the catalyst is not supplied to the substrate.
