  • Patent number: 8931433
    Abstract: The present invention aims at providing a plasma processing apparatus for performing a plasma processing on a planar substrate body to be processed, the apparatus being capable of generating the plasma with good uniformity and efficiently using the plasma, and having a high productivity. That is, the plasma processing apparatus according to the present invention includes: a vacuum chamber; one or plural antenna supporters (plasma generator supporters) projecting into the internal space of the vacuum chamber; radio-frequency antennas (plasma generators) attached to each antenna supporter; and a pair of substrate body holders provided across the antenna supporter in the vacuum chamber, for holding a planar substrate body to be processed.

  • Publication number: 20110220026
    Abstract: A plasma processing device according to the present invention includes a plasma processing chamber consisting of a vacuum container, a pair of substrate holders standing opposite each other in the plasma processing chamber, a plurality of first reaction gas tubes provided between the two substrate holders, and a plurality of second reaction gas tubes provided between the plurality of first reaction gas tubes and each of the two substrate holders. The first reaction gas tubes, which are made of an electrically conductive material, are electrically connected to a first radio-frequency power source or second radio-frequency power source. The first reaction gas tubes double as a radio-frequency antenna, while the second reaction gas tubes double as an electrode.

  • Publication number: 20100272550
    Abstract: The present invention provides a substrate holding mechanism capable of assuredly holding a substrate and delivering/receiving it: a substrate holding mechanism including a substrate holding unit for holding a rectangular substrate, comprising: a plurality of substrate holding rollers provided at positions corresponding to two opposite sides of the substrate on the substrate holding unit and pivotally supported by the substrate holding unit; and a roller driver for rotating the substrate holding rollers, wherein: the substrate holding roller comprises a cylinder part and a holding flange provided along a portion of a circumference of each end of the cylinder part; and each of the substrate holding rollers is rotated by the roller driver so that a state of holding edges of the substrate by the holding flange and a state of releasing the edges can be switched in accordance with a rotation angle of the substrate holding rollers.
