  • Patent number: 11515152
    Abstract: There is provided a technique that includes forming a film on a substrate by performing a cycle a predetermined number of times, the cycle including: (a) supplying a precursor gas to the substrate in a process container of a substrate processing apparatus via a first pipe made of metal; (b) supplying an oxygen-containing gas to the substrate in the process container via a second pipe made of metal, wherein a fluorine-containing layer is continuously formed on an inner surface of the second pipe; and (c) supplying a nitrogen-and-hydrogen-containing gas to the substrate in the process container via the second pipe.
    Type: Grant

  • Patent number: 9963785
    Abstract: Disclosed is a method of manufacturing a semiconductor device including: performing a pre-process to a metal film or a GST film by supplying a first processing gas to a substrate, on a surface of which the metal film or the GST film is formed, without supplying a second processing gas; and performing a formation process to the substrate to which the pre-process has been performed such that a film is formed on the metal film or the GST film by executing at least one cycle of alternately (i) supplying the first processing gas, and (ii) supplying the second processing gas that is activated by plasma excitation.

  • Patent number: 9593422
    Abstract: Disclosed is a method of manufacturing a semiconductor device including: performing a pre-process to a substrate, on a surface of which a metal film or a GST film is formed, such that a first film is formed on the metal film or the GST film by executing at least one cycle of alternately performing (i) supplying a first processing gas, and (ii) supplying a second processing gas that is not activated by plasma excitation; and performing a formation process to the substrate to which the pre-process has been performed such that a second film is formed on the first film by executing at least one cycle of alternately (i) supplying the first processing gas, and (ii) supplying the second processing gas that is activated by plasma excitation.

  • Patent number: 9175395
    Abstract: Disclosed is a substrate processing apparatus including: a processing chamber; plural buffer chambers; a first processing gas supply system that supplies a first processing gas to the processing chamber; a second processing gas supply system that supplies a second processing gas to the buffer chambers; a RF power source; plasma-generating electrodes in the buffer chambers; a heating system; and a controller that controls the first and second processing gas supply systems, the power source, and the heating system to expose the substrate having a metal film thereon to the first processing gas, and the second processing gas that is activated in the plural buffer chambers with an application of RF power to the electrodes and that is supplied from the buffer chambers to the processing chamber to form a film on the metal film while heating the substrate to a self-decomposition temperature of the first processing gas or lower.
