Claim:
1. A method of depositing a compound semiconductor material on a substrate using a halide vapor phase epitaxy system, comprising: metering and controlling a flow rate of a precursor liquid from a source of the precursor liquid into a vaporizer, the precursor liquid comprising at least one of GaCl maintaining a temperature of the precursor liquid within a range extending from about 90° C. to about 100° C. between the source of the precursor liquid and the vaporizer; heating the precursor liquid within the vaporizer to at least about 400° C. and vaporizing the precursor liquid within the vaporizer to form a first precursor vapor; flowing the first precursor vapor out from the vaporizer, through a precursor gas furnace disposed at least partially within a reaction chamber, and to a region proximate a surface of a workpiece substrate within the reaction chamber, the precursor gas furnace comprising: separately flowing a second precursor vapor into the reaction chamber; and depositing a compound semiconductor material on the surface of the workpiece substrate within the reaction chamber, the compound semiconductor material comprising at least one element from the first precursor vapor and at least one element from the second precursor vapor.
