| 摘要 |
Hybrid MOCVD or HVPE epitaxial system for in-situ epitaxially growth of group III-nitride layers and group IV semiconductor layers and/or group IV compounds. A hybrid deposition chamber is coupled to each of a first and second precursor delivery system to grow both a transition film comprising either group IV semiconductor or group IV compound and a film comprising a group III-nitride on the transition film. In one embodiment, the first precursor delivery system is coupled to both a silicon precursor and a second group IV precursor while the second precursor delivery system is coupled to a metalorganic precursor. In embodiments, a layer comprising a silicon semiconductor is deposited over a substrate and a group III-nitride epitaxial film is then deposited in-situ over the substrate.
