  • Patent number: 10181406
    Abstract: In an inductively-coupled plasma torch unit, a coil, a first ceramic block, and a second ceramic block are arranged parallel to one another, and an elongated chamber has an annular shape. Plasma generated inside the chamber is ejected toward a substrate through an opening portion in the chamber. The substrate is processed by relatively moving the elongated chamber and the substrate in a direction perpendicular to a longitudinal direction of the opening portion. A rotating ceramic pipe having a cylindrical shape is provided so as to cause a refrigerant to flow into a cavity formed inside the ceramic pipe. Accordingly, it becomes possible to apply greater high-frequency power, thereby enabling fast plasma processing.
