Abstract
A film forming method includes: preparing a substrate having a surface on which a first film containing boron and a second film made of a material different from that of the first film are formed; supplying a raw material gas, which contains halogen and an element X other than halogen, to the surface of the substrate; and supplying a plasmarized reaction gas, which contains oxygen, to the surface of the substrate, wherein a third film as an oxide film of the element X is selectively formed on the second film with respect to the first film by alternately supplying the raw material gas and the plasmarized reaction gas.
