  • Patent number: 11885015
    Abstract: A deposition method includes preparing a substrate having an insulating film formed thereon; forming a molybdenum film on the insulating film by supplying a molybdenum-containing gas and a reducing gas to the substrate; and heat-treating the substrate having the molybdenum film formed on the insulating film, without exposing the substrate to atmospheric air.
    Type: Grant

  • Publication number: 20230009720
    Abstract: A method of forming a film is performed in a heat treatment apparatus that includes a processing container, a tubular member provided in the processing container, a heater configured to heat an inside of the processing container, and a gas supply. The method includes: providing a substrate in the tubular member; adjusting a temperature inside the tubular member by the heater; and after adjusting the temperature, supplying a gas containing a film-forming gas from the gas supply into the processing container to form a film on the substrate. In the adjusting the temperature, a gas containing a heat transfer gas is supplied from the gas supply into the processing container.

  • Publication number: 20220389569
    Abstract: A deposition method includes preparing a substrate having an insulating film formed thereon, forming a first molybdenum film on the insulating film by supplying a molybdenum-containing gas and a reducing gas to the substrate while the substrate is heated to a first temperature, and forming a second molybdenum film on the first molybdenum film by supplying the molybdenum-containing gas and the reducing gas to the substrate while the substrate is heated to a second temperature that is higher than the first temperature.
