  • Patent number: 11414742
    Abstract: There is provided a substrate processing apparatus which includes: a substrate mounting table installed in a vacuum vessel; a gas supply part configured to supply a processing gas into the vacuum vessel; a vacuum-exhausting part configured to exhaust the interior of the vacuum vessel; an elevating member configured to lift up and down a substrate while holding the substrate mounted on the mounting table; and a control part configured to output a control signal to execute a first step of supplying the processing gas onto the substrate and setting an internal pressure of the vacuum vessel to a first pressure, a second step of changing the internal pressure to a second pressure lower than the first pressure, and a third step of lifting up the substrate from the mounting table after the first step and before the second step or in parallel with the second step.

  • Patent number: 10242878
    Abstract: A substrate processing method is for forming a metal film on a target substrate by using a plasma. The method includes loading a target substrate having a silicon-containing layer on a surface thereof into a processing chamber which is pre-coated by a film containing a metal, introducing hydrogen gas and a gaseous compound of the metal and halogen into the processing chamber, generating a plasma, and forming a metal film on the target substrate. The method further includes performing a first reduction process of forming an atmosphere of a plasma obtained by activating hydrogen gas in the processing chamber, unloading the target substrate from the processing chamber, performing a second reduction process of forming an atmosphere of a plasma obtained by activating hydrogen gas in the processing chamber, and loading a next target substrate into the processing chamber.
