    摘要: An apparatus for the continuously forming a crystalline ribbon from molten silicon is introduced. A heater is provided including a pair of spaced planar electrodes parallel to the surface of the molten silicon for capacitively coupling radio frequency electrical currents into the material causing a ribbon of material to melt along a zone. A conductive electrode in thermal contact with a respective cooler and a dielectric layer between the conductive and semi-conductive electrodes is provided. A closeable transfer lock defining a chamber configured to accept a portion of the crystalline ribbon is used to transport a portion of the crystalline ribbon out of apparatus while recycling inert gas used in the system.

    摘要: The present invention relates to methods and apparatus that are optimized for producing Group III-N (nitrogen) compound semiconductor wafers and specifically for producing GaN wafers. Specifically, the methods relate to substantially preventing the formation of unwanted materials on an isolation valve fixture within a chemical vapor deposition (CVD) reactor. In particular, the invention provides apparatus and methods for limiting deposition/condensation of GaCl3 and reaction by-products on an isolation valve that is used in the system and method for forming a monocrystalline Group III-V semiconductor material by reacting an amount of a gaseous Group III precursor as one reactant with an amount of a gaseous Group V component as another reactant in a reaction chamber.
