Abstract:
Atomic Layer Deposition (ALD) is used for heteroepitaxial film growth at reaction temperatures ranging from 80-400° C. The substrate and film materials are preferably matched to take advantage of Domain Matched Epitaxy (DME). A laser annealing system is used to thermally anneal deposition layer after deposition by ALD. In preferred embodiments, a silicon substrate is overlaid with an AlN nucleation layer and laser annealed. Thereafter a GaN device layer is applied over the AlN layer by an ALD process and then laser annealed. In a further example embodiment, a transition layer is applied between the GaN device layer and the AlN nucleation layer. The transition layer comprises one or more different transition material layers each comprising a Al x Ga 1-x N compound wherein the composition of the transition layer is continuously varied from AlN to GaN.

Claim (Index 9):
The method of  claim 7  wherein the step of applying the transition layer comprises applying a plurality of different material layers wherein each of the plurality of different material layers comprises an Al x Ga 1-x N compound and wherein each of the plurality of different Al x Ga 1-x N compounds is applied by a different atomic layer deposition method, and wherein the heating step includes\n performing a single first heating step to thermally anneal an entire thickness of the aluminum nitride nucleation layer, \n performing a plurality of second heating steps, one to thermally anneal an entire thickness of each one of the plurality of different material layers of the transition layer, and \n performing a third heating step to thermally anneal an entire thickness of the gallium nitride device layer.
