Abstract:
1. A method for epitaxial deposition of a Group III-V semiconductor material, which comprises introducing a gaseous Group III trichloride precursor and a gaseous Group V component into a reaction chamber, wherein the gaseous Group III trichloride precursor is continuously provided at a mass flow of at least 50 g Group III element/hour; reacting an amount of the introduced gaseous Group III trichloride precursor as one reactant with an amount of the introduced gaseous Group V component as another reactant in the reaction chamber to deposit the semiconductor material in an amount sufficient for high volume production at a deposition rate of at least 50 g Group III element per hour for a period of at least 48 hours; removing exhaust gases including unreacted Group III trichloride precursor, unreacted Group V component and reaction byproducts; and heating the removed exhaust gases to temperatures between about 130° C. and about 160° C. so as to reduce condensation thereof and enhance manufacture of the semiconductor material.
