    Abstract: A scanning magnet that deflects a charged particle beam has a winding U provided with grooves SL1 and SL4 provided at facing positions. A passing direction of a conductive wire forming the winding U passes through the groove SL1 in a ?-axis positive direction, and passes through the groove SL4 in a ?-axis negative direction. The winding U has a loop path SL1-SL4 in which the groove SL1 is directed to the ?-axis positive direction, and the groove SL4 is directed to the ?-axis negative direction. When a current flows in the ?-axis positive direction in a winding section U+ disposed in the groove SL1, a current flows in the ?-axis negative direction in a winding section U? disposed in the groove SL4. A yoke, the winding U, a winding V, and a winding W have a 120° rotationally symmetric structure with respect to a central axis of the yoke.

  • Publication number: 20210327709
    Abstract: A gate insulator film made of silicon dioxide or gallium oxide is formed on a gallium nitride (GaN) substrate. The GaN substrate is preheated by irradiation with light from halogen lamps, and the surface of the substrate including the gate insulator film is heated to a high temperature for an extremely short time by irradiation with a flash of light from flash lamps. Heating the substrate surface including the gate insulator film in an extremely short heat treatment time prevents the desorption of nitrogen from GaN and makes it possible to reduce the traps existing at the interface between the gate insulator film and GaN without diffusing gallium into the gate insulator film.

  • Publication number: 20210159099
    Abstract: A ring support is attached to an inner wall surface of a chamber that houses a semiconductor wafer to support a susceptor. When the semiconductor wafer is placed on the susceptor, an inner space of the chamber is separated into an upper space and a lower space. Particles are likely to accumulate on a lower chamber window as a floor part of the chamber. However, since the upper space and the lower space are separated, the semiconductor wafer can be prevented from being contaminated by the particles flowing into the upper space and adhering to a surface of the semiconductor wafer even when the particles on the lower chamber window are blown up by irradiation with flash light.
