摘要： An ion source is disclosed having an elongated slit for providing a ribbon ion beam for use in an ion implantation system. The source comprises a coaxial inductive coupling antenna for RF excitation of plasma within a cylindrical source housing, as well as circumferential magnets disposed within the housing for generating azimuthal multi-cusped magnetic fields for plasma confinement. Also disclosed is a liner for the housing interior providing thermal barrier between the plasma and the outer housing wall so as to mitigate or reduce condensation within the plasma confinement chamber.

摘要： The invention provides systems and methods for the deposition of an improved diamond-like carbon material, particularly for the production of magnetic recording media. The diamond-like carbon material of the present invention is highly tetrahedral, that is, it features a large number of the sp3 carbon-carbon bonds which are found within a diamond crystal lattice. The material is also amorphous, providing a combination of short-range order with long-range disorder, and can be deposited as films which are ultrasmooth and continuous at thicknesses substantially lower than known amorphous carbon coating materials. The carbon protective coatings of the present invention will often be hydrogenated. In a preferred method for depositing of these materials, capacitive coupling forms a highly uniform, selectively energized stream of ions from a dense, inductively ionized plasma. Such inductive ionization is enhanced by a relatively slow moving (or nullquasi-staticnull) magnetic field, which promotes resonant ionization and ion beam homogenization.

摘要： A surface ion source apparatus (10) creates a high purity ion beam (44) of molecules of metal compounds having a lower ionization energy than the metal they contain. Low energy dispersion in the ion beam and currents on the order of one ampere are attainable over long duration operation. Rhenium screen (12) is used in the ion source and related catalyzer (31). Temperatures vary in the range of 700 to 2500 degrees centigrade and a preferred vacuum pressure of 10.sup.-5 torr, or lower, is used. Wear and corrosion resistance of a wide variety of materials is greatly enhanced through ion deposition and/or implantation with the disclosed apparatus and methods. This high output ion source is also useful for electronic propulsion, separation of isotopes and production of electricity by forcing ions through a transverse magnetic field, such as used with a magnetohydrodynamic generator.

摘要： Combining an evaporation source and an ion beam source to provide a crucible anode surface, and heating that crucible anode surface to a high enough temperature to cause evaporation of anode material, provides for emission of atoms and ions selectively and independently controllable and directed along the identical path. A high melting point material auxiliary anode, connected to the crucible anode by a variable resistance, provides independent control of the vapor flux by selectively shifting the discharge current from auxiliary anode to crucible anode. The crucible anode contains the material which is to be evaporated. A gas plasma discharge is supplied between a heated cathode filament and the heated crucible anode. Electrons carrying a discharge current bombard the crucible anode material surface, causing a temperature rise which causes an increase in discharge current. At a high enough discharge current level, the anode material in the crucible anode melts and vaporizes, forming a stream which passes through an extraction grid to deposit vaporized anode material on a substrate. The gas discharge generates ions, which are accelerated by voltages on the anodes, forming an ion beam which also strikes the substrate. The flux of the ion beam is controlled by the discharge current. The ion energy is controlled by the anode power supply. Shifting a portion of the discharge current from the auxiliary anode to the crucible anode increases the amount of vapor flux for a given ion flux.

摘要： An apparatus and method for the creation of negative ion beams is disclosed. The apparatus includes an RF ion source, having an extraction aperture. An antenna disposed proximate a dielectric window is energized by a pulsed RF power supply. While the RF power supply is actuated, a plasma containing primarily positive ions and electrons is created. When the RF power supply is deactivated, the plasma transforms into an ion-ion plasma. Negative ions may be extracted from the RF ion source while the RF power supply is deactivated. These negative ions, in the form of a negative ribbon ion beam, may be directed toward a workpiece at a specific incident angle. Further, both a positive ion beam and a negative ion beam may be extracted from the same ion source by pulsing the bias power supply multiple times each period.

摘要： An apparatus for the creation of high current ion beams is disclosed. The apparatus includes an ion source, such as a RF ion source or an indirectly heated cathode (IHC) ion source, having an extraction aperture. Disposed proximate the extraction aperture is a bias electrode, which has a hollow center portion that is aligned with the extraction aperture. A magnetic field is created along the perimeter of the hollow center portion, which serves to contain electrons within a confinement region. Electrons in the confinement region energetically collide with neutral particles, increasing the number of ions that are created near the extraction aperture. The magnetic field may be created using two magnets that are embedded in the bias electrode. Alternatively, a single magnet or magnetic coils may be used to create this magnetic field.
