Patent ID: 7955569

Claim:
A high temperature metal halide producing reactor producing substantially pure metal halides in a controlled manner for commercial scale reactors, comprising: an external housing constructed from a pipe segment consisting of external walls, two ends, and vacuum seals in at least one end, allowing inert atmosphere and/or vacuum conditions within said external housing; a non-reactive sealed container formed from a cylinder with a top and a bottom supported by supporting means inside said external housing; said pipe segment being at least 6 times the length of the cylinder, and said pipe segment having a diameter that is sized to accommodate the cylinder plus at least 2 centimeters of inside diameter; said non-reactive sealed container being supplied with at least one inlet port and at least one exit port, both of non-reactive construction, said inlet port having fluid communication with a fluid source external to said external housing and said exit port having fluid communication with a furnace outside said external housing; at least one internal supporting media held by holding means within said container; a fill of a metal or a metallic compound within said sealed non-reactive container upon said supporting media in a form allowing flow of gas through said fill; and heating means surrounding said external housing and extending beyond top and bottom positions of said non-reactive sealed container within said external housing, said external housing having sufficient length beyond the length of said heating means to allow cooling of said walls of said external housing such that vacuum seals may be maintained at either end of said external housing; wherein said non-reactive sealed container is heated to specific temperatures and a gaseous halogen or halogen containing compound is introduced into said non-reactive sealed container by said inlet port, allowed to flow through said fill of the metal or metallic compound, reacting therewith, to form said metal halide and said metal halide then exits through said exit port into a CVD, PECVD, PPECVD or other said furnace separate from said halide producing reactor and with a separate heating means with means for deposition of said metal component of said metal halide at temperatures different than those of said halide producing reactor.
