  • Publication number: 20140060572
    Abstract: In a plasma processing apparatus, a mounting table is provided in a processing chamber, and a remote plasma generating unit is configured to generate an excited gas by exiting a hydrogen-containing gas. The remote plasma generating unit has an outlet for discharging the excited gas. A diffusion unit is provided to correspond to the outlet of the remote plasma generating unit and serves to receive the excited gas flowing from the outlet and diffuse the hydrogen active species having a reduced amount of hydrogen ions. An ion filter is disposed between the diffusion unit and the mounting table while being separated from the diffusion unit. The ion filter serves to capture the hydrogen ions contained in the hydrogen active species diffused by the diffusion unit and allow the hydrogen active species having a further reduced amount of hydrogen ions to pass therethrough the mounting table.

  • Patent number: 8277889
    Abstract: A film formation method is disclosed for depositing a metal film on a target substrate by supplying a metal carbonyl source in gas phase to a surface of the target substrate and decomposing the source near the surface of the target substrate. The method includes a step of preferentially decomposing the metal carbonyl source in an area near the outer peripheral portion of the target substrate when the metal film is being deposited on the surface of the target substrate. As a result, a CO concentration in the atmosphere is increased locally near the outer peripheral portion of the target substrate and the depositing of the metal film on the outer peripheral portion is better controlled.
