TEMPERATURE-CONTROLLED PURGE GATE VALVE FOR CHEMICAL VAPOR DEPOSITION CHAMBER |
摘要 |
<p>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.</p> |
