Patent number: 10269562Abstract: The invention provides the use of at least one binary group 15 element compound of the general formula R1R2E-E?R3R4 (I) or R5E(E?R6R7)2 (II) as the educt in a vapor deposition process. In this case, R1, R2, R3 and R4 are independently selected from the group consisting of H, an alkyl radical (C1-C10) and an aryl group, and E and E? are independently selected from the group consisting of N, P, As, Sb and Bi. This use excludes hydrazine and its derivatives. The binary group 15 element compounds according to the invention allow the realization of a reproducible production and/or deposition of multinary, homogeneous and ultrapure 13/15 semiconductors of a defined combination at relatively low process temperatures. This makes it possible to completely waive the use of an organically substituted nitrogen compound such as 1.Type: GrantFiled: September 25, 2015Date of Patent: April 23, 2019Assignee: PHILIPPS-UNIVERSITÄT MARBURGInventors: Carsten Von Haenisch, Kerstin Volz, Wolfgang Stolz, Eduard Sterzer, Andreas Beyer, Dominik Keiper, Benjamin Ringler

Patent number: 10249491Abstract: 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 AlxGa1-xN compound wherein the composition of the transition layer is continuously varied from AlN to GaN.Type: GrantFiled: April 2, 2018Date of Patent: April 2, 2019Assignee: Ultratech, Inc.Inventors: Ganesh Sundaram, Andrew M.
