Method for implanting single or multiply charged ions into a surface of a treated object and device for implementation of the method
A method for single or multiply charged ion implantation into a surface of a treated object, and a device for implementing the implantation method, the method including: directing towards the surface of the treated object an ion beam produced by an ion source of the electronic cyclotron resonance type; producing at least one primary electron beam and directing the primary electron beam so that it passes through the ion beam; and producing a secondary electron beam by reflecting the primary electron beam onto a target once the primary electron beam has traversed the ion beam, the target being oriented such that the secondary electron beam falls onto the surface of the treated object.
Ion source crucible for solid feed materials
An ion source with a crucible is disclosed. In some embodiments, the crucible is disposed in one of the ends of the ions source, opposite the cathode. In other embodiments, the crucible is disposed in one of the side walls. A feed material, which may be in solid form is disposed in the crucible. In certain embodiments, the feed material is sputtered by ions and electrons in the plasma. In other embodiments, the feed material is heated so that it vaporizes. The ion source may be oriented so that the crucible is disposed in the lowest wall so that gravity retains the feed material in the crucible.
METHODS AND SYSTEMS FOR PLASMA DEPOSITION AND TREATMENT
An ion beam treatment or implantation system includes an ion source emitting ion beams. The ion source includes a microwave source and a curved waveguide conduit having openings therein. The waveguide conduit is coupled to the microwave source for transmitting microwaves from the microwave source through the plurality of openings. The ion source also includes a curved plasma chamber in communication with the waveguide conduit through the openings. The plasma chamber receives through the openings microwaves from the waveguide conduit. The plasma chamber includes magnets disposed in an outer wall of the plasma chamber for forming a magnetic field in the plasma chamber. The plasma chamber further includes a charged cover at a side of the chamber opposite the side containing the openings. The cover includes extraction holes through which the ion beams are extracted.
Tetrode extraction apparatus for ion source
An electrode system for an ion source has a source electrode that defines a source aperture in an ion source chamber, and is coupled to a source power supply. A first ground electrode defines a first ground aperture that is electrically coupled to an electrical ground potential and extracts ions from the ion source. A suppression electrode is positioned downstream of the first ground electrode and defines a suppression aperture that is electrically coupled to a suppression power supply. A second ground electrode is positioned downstream of the suppression electrode and defines a second ground aperture. The first and second ground electrodes are fixedly coupled to one another and are electrically coupled to the electrical ground potential.
METHODS AND SYSTEMS FOR PLASMA DEPOSITION AND TREATMENT
An ion beam treatment or implantation system includes an ion source emitting a plurality of parallel ion beams having a given spacing. A first lens magnet having a non-uniform magnetic field receives the plurality of ion beams from the ion source and focuses the plurality of ion beams toward a common point. The system may optionally include a second lens magnet having a non-uniform magnetic field receiving the ion beams focused by the first lens magnet and redirecting the ion beams such that they have a parallel arrangement having a closer spacing than said given spacing in a direction toward a target substrate.
Varied component density for thermal isolation
A system that utilizes a component that controls thermal gradients and the flow of thermal energy by variation in density is disclosed. Methods of fabricating the component are also disclosed. The component is manufactured using additive manufacturing. In this way, the density of different regions of the component can be customized as desired. For example, a lattice pattern may be created in the interior of a region of the component to reduce the amount of material used. This reduces weight and also decreases the thermal conduction of that region. By using low density regions and high density regions, the flow of thermal energy can be controlled to accommodate the design constraints.
Plasma Source
The invention concerns a plasma source including a quarter wave antenna (204) located in a cylindrical enclosure (202) provided with an opening (208) opposite the end of the antenna (204). The diameter (d) of the antenna (204) is in the range from one third to one quarter of the inner diameter (d.sub.1) of the enclosure (202). The distance (l) between the end of the antenna (204) and the opening (208) is in the range from to 5/3 of the diameter (d) of the antenna (204).

Performance extraction set
An extraction set including an extraction plate, a blocker and the holding mechanism for the blocker is disclosed. The extraction set includes an extraction plate that may be constructed of titanium coated with a ceramic material. The extraction plate is attached to the ion source using pins. The extraction plate also includes raised outline in its inner surface which is used to secure the blocker to the inner surface of the extraction plate. The ends of the blocker are secured by two holders disposed on opposite sides of the extraction aperture. The mechanism used for attaching the extraction plate to the ion source also improves the temperature uniformity of the extraction plate.
