Abstract
A hybrid deposition system includes a reactor chamber, at least one heating unit, a first reagent gas source, a metallo-organic source, a second reagent gas source, and a valve unit for stopping flow of gas from the metallo-organic source. The hybrid incorporates features of both metal-organic chemical vapor deposition (MOCVD) and hydride vapor-phase epitaxy (HVPE). The hybrid system may be operated in MOCVD mode, in HVPE mode, or in both MOCVD and HVPE mode simultaneously. The system may be switched between deposition modes without interrupting deposition, or removing the sample from the reactor chamber. The at least one heating unit may be moved relative to the reactor chamber, or vice versa, for easily and rapidly adjusting the temperature of the reactor chamber. A method for forming at least one epitaxial layer of a III-V compound on a non-native substrate in which deposition is performed by two different techniques in the same reactor chamber. The two different deposition techniques, for example, MOCVD and HVPE, may be performed in the same reactor chamber, consecutively and concurrently.
