  • Patent number: 9299529
    Abstract: A repeller structure comprises a target member configured to be sputtered by a plasma to emit given ions, and provided with a through-hole penetrating between a sputterable surface and a reverse surface thereof, and a repeller body which supports the target member while being inserted in the through-hole of the target member, and has a repeller surface exposed on the side of the sputterable surface through the through-hole. The target member is made of a material selected from the group consisting of gallium oxide, gallium nitride, gallium phosphide, gallium arsenide and gallium fluoride.

  • Patent number: 8680491
    Abstract: Provided is a method of controlling an ion implantation apparatus 100 which includes: a mass separator 3 for sorting out and outputting ions having a specific mass number and valence from an ion beam IB extracted from an ion source 2; an acceleration tube 4 for accelerating or decelerating the ion beam IB output from the mass separator 3; and an energy separator 5 for sorting out and outputting ions having a specific energy from the ion beam IB output from the acceleration tube 4. The method comprises, during an acceleration mode, controlling an acceleration voltage VA such that it is prevented from becoming 0 kV.

  • Patent number: 4915977
    Abstract: A method of forming a diamond film on a substrate wherein hydrogen, a hydrocarbon series gas, an inert gas, an organic compound series gas or a mixture of such gases is introduced into a vacuum vessel to contact a substrate and carbon is evaporated by are discharge at a carbon cathode while applying a voltage to the substrate to deposit carbon on the substrate thus forming a diamond film on the substrate. A silicon series gas, a germanium series gas or a mixture thereof may be also introduced into the vessel with the foregoing gas or gases. While the carbon is being deposited on the substrate, thermoelectrons may also be supplied onto the substrate, and, further, high frequency discharge may be generated in a space between the substrate and the cathodes.
