Abstract:
1. A thermalizing gas injector for injecting one or more gases into a reaction chamber of a deposition system, comprising: an inlet; a thermalizing conduit; a liquid container holding liquid metal reagent therein; an outlet; a pathway extending from the inlet, through the thermalizing conduit to an interior space within the liquid container, and from the interior space within the liquid container to the outlet, the thermalizing conduit having a length greater than a shortest distance between the inlet and the liquid container; and at least one active heating element and at least one passive heating element disposed proximate the thermalizing conduit and the liquid container, the thermalizing conduit surrounding a generally cylindrical space in which the at least one passive heating element is disposed, the at least one active heating element surrounding the thermalizing conduit and the at least one passive heating element, the at least one active heating element and the at least one passive heating element configured to provide thermal energy for heating one or more gases within the thermalizing conduit and the liquid container and to heat one or more gases within the at least one of the thermalizing conduit and the liquid container to a temperature between about 500° C. and about 1,000° C., the at least one passive heating element comprised of at least one of aluminum nitride (AlN), silicon carbide (SIC), and boron carbide (B
