摘要： Disclosed is a vapor source assembly comprising a means for supporting at least one material to be vaporized, a plurality of electron-beam guns for producing electron beams, and a deflecting means for producing a magnetic field to deflect each electron beam through an arcuate path from its electron-beam gun to the material to be vaporized. The deflecting means includes a plurality of pairs of pole pieces positioned such that a north pole piece and a south pole piece, are on opposite sides of each electron-beam gun, and a plurality of magnetic means including magnets for interconnecting the south pole piece of each successive electron-beam gun with the north pole piece of the next successive electron-beam gun so as to form a single magnetic circuit. In preferred embodiments, the electron-beam guns are positioned below the maximum level of material in a cluster of crucibles, and two long pole pieces extend on opposite sides of the crucibles, but no pole piece extends between adjacent crucibles. A magnetic means for sweeping the electron beams may also be included.

摘要： A mechanically stacked module package is described. The package permits the effective mechanical stacking of two solar cells in a compact arrangement. The design also permits the easy wiring of the package into a voltage matching configuration for module wiring thus eliminating the problems of current matching the top and bottom cells. The package design can be used with any mechanically stacked cells although the design is most suitable for concentrator solar cell configurations where the removal of heat to avoid degradation and shortening of lifetime is a major concern.

摘要： Methods and apparatus are provided for static-biasing a pre-metalized non-conductive substrate within a process chamber. A substrate holder that holds a pre-metalized non-conductive substrate is engaged by a lift mechanism that provides movement of the substrate in a first, upward direction to a contact position within the process chamber and in a second direction to a non-contact position. When the substrate holder is moved to the contact position, the substrate electrically engages a conductive spring-loaded compliance mechanism that is mounted in a fixed position within the process chamber. The spring-loaded compliance mechanism is connected to a bias-voltage feed-through for the process chamber that applies a bias voltage to the substrate via the spring-loaded compliance mechanism.

摘要： An injection block having a plurality of geometrically arranged injection sources for gaseous Group III metal organic compounds is oriented substantially perpendicular to the placement of at least one semiconductor wafer substrate within a vacuum reaction chamber. The injector sources are sized to provide disbursing flow of the compounds capable of depositing a layer of about 5% uniform thickness or less over substantially the entire semiconductor wafer. An injection source of Group V compounds is located centrally within the geometrically arranged injection sources for the Group III compounds. The Group V injection source is sized to supply an excess of the Group V compounds required to react with the Group III compounds in order to form Group III-V semiconductor layers on the substrate and partition the Group III sources into groups having substantially equal numbers of injection sources. An excess of Group V comounds is injected. The vacuum within the reaction chamber is adjusted at predetermined flow rates of the Group III compounds such that a mean-free path of the Group III compounds is greater than the distance from the injection source of the Group III compounds to the substrate. The substrate is heated to a temperature to which a reaction proceeds. The unreacted Group III compounds are exhausted from the vacuum chamber adjacent the edges of a substrate holder facing the top of the chamber opposite to the injection sources. In this manner, the disbursing flow of Group III compounds from the geometric arrangement of sources uniformly overlaps substantially the entire substrate and the algebraic sum of the fluxes from the Group III compound sources remains constant across the area of the substrate upon which the layer is to be deposited.

摘要： A planar magnetron sputtering apparatus is provided with an additional, variable magnetic field normal to and substantially throughout the erosion region of a cathode plate. Application of the foregoing variable magnetic field effects continuous variations in the general location of the points at which magnetic lines of flux are parallel to the cathode plate which correspondingly results in variations in the points of maximum cathode plate erosion. By producing a less acute erosion pattern over a wider cathode plate area, a greater portion of the cathode plate material may be sputtered from any particular planar cathode plate.
