  • Patent number: 11840759
    Abstract: A method includes: forming a titanium nitride base film containing silicon by alternately repeating: precipitation of titanium nitride by alternately and repeatedly supplying a titanium-containing gas, and supplying a nitriding gas to a substrate on which a recess is formed; and precipitation of silicon nitride by alternately and repeatedly supplying a silicon-containing gas, and supplying a nitriding gas to the substrate; and subsequently, forming a tungsten film so as to bury tungsten in the recess in which the titanium nitride base film is formed, by alternately and repeatedly supplying a raw material gas containing a tungsten raw material and a reaction gas reacting with the raw material gas, to the substrate. A supply flow rate of the silicon-containing gas is adjusted so that a content of the silicon in the titanium nitride base film is high on an opening side rather than on an inner side of the recess.
