  • Publication number: 20240038499
    Abstract: An ion source includes a vaporizer, a plasma chamber, and a controller. The vaporizer produces a reaction product by supplying, through a first gas supply line to a crucible in which a solid material is installed, a reactive gas that reacts with the solid material, and vaporizes the reaction product by heating the crucible with a heater. The plasma chamber is supplied with a vapor from the vaporizer through a vapor supply line, and has a second gas supply line connected to the plasma chamber separately from the vapor supply line. The controller controls the heater to heat the crucible while a gas is being supplied from the second gas supply line to the plasma chamber and stops a supply of the reactive gas through the first gas supply line to the crucible.

  • Patent number: 10470284
    Abstract: A plasma source is provided. The plasma source includes a chamber body inside which plasma is generated, a first mirror magnet, a second mirror magnet, and a cusp magnet provided around the chamber body and spaced apart in a axial direction thereof, each comprising permanent magnets radially spaced apart from each other to form spaces between adjacent permanent magnets thereof; and a cooling medium flow passage provided in the spaces that passes a cooling medium for cooling the chamber body.

  • Patent number: 10199201
    Abstract: A plasma source is provided. The plasma source includes a chamber body, a supply passage, a vacuum connector, an antenna, a first insulator, a second insulator, and a conductor. The chamber body has an opening for emitting ions or electrons. The supply passage penetrates through a first peripheral wall of the chamber body. The vacuum connector is provided in a second peripheral wall of the chamber body at a position opposed to the opening. The antenna has a base end connected to the vacuum connector, and extends inside the chamber body toward the opening. The first insulator covers a first region of the antenna at a distal end of the antenna inside the chamber body. The second insulator covers a second region of the antenna at the base end of the antenna inside the chamber body. The conductor covers the second insulator.
