METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE AND RECORDING MEDIUM
A method of manufacturing a semiconductor device includes forming a metal-containing film including a first element that is a metal element and a second element by performing a predetermined number of times in a time-division manner a cycle of supplying an organic metal source gas containing the first element to a substrate, supplying a halogen-based metal source gas containing the first element to the substrate and supplying a reaction gas, which contains the second element and which reacts with the first element, to the substrate, wherein a value of film stress of the metal-containing film is controlled by controlling at least one value of a supply flow rate and a supply time of the organic metal source gas in the act of supplying an organic metal source gas.
1 . A method of manufacturing a semiconductor device comprising forming a metal-containing film including a first element that is a metal element and a second element by performing a predetermined number of times in a time-division manner a cycle comprising:
supplying an organic metal source gas containing the first element to a substrate;
supplying a halogen-based metal source gas containing the first element to the substrate; and
supplying a reaction gas, which contains the second element and which reacts with the first element, to the substrate,
wherein a value of film stress of the metal-containing film is controlled by controlling at least one value of a supply flow rate and a supply time of the organic metal source gas in the act of supplying an organic metal source gas.
2 . The method of claim 1 , wherein the act of supplying an organic metal source gas, the act of supplying a halogen-based metal source gas, and the act of supplying a reaction gas are sequentially performed a predetermined number of times in a time-division manner.
3 . The method of claim 1 , wherein the act of supplying a halogen-based metal source gas, the act of supplying an organic metal source gas, and the act of supplying a reaction gas are sequentially performed a predetermined number of times in a time-division manner.
4 . The method of claim 1 , wherein the metal-containing film is a thin film formed as a hard mask for etching an etching target film formed on the substrate.
