Abstract: Semiconductor devices including an elevated or raised doped crystalline structure extending from a device layer are described. In embodiments, III-N transistors include raised crystalline n+ doped source/drain structures on either side of a gate stack. In embodiments, an amorphous material is employed to limit growth of polycrystalline source/drain material, allowing a high quality source/drain doped crystal to grow from an undamaged region and laterally expand to form a low resistance interface with a two-degree electron gas (2DEG) formed within the device layer. In some embodiments, regions of damaged GaN that may spawn competitive polycrystalline overgrowths are covered with the amorphous material prior to commencing raised source/drain growth.

Abstract: Crystalline heterostructures including an elevated crystalline structure extending from one or more trenches in a trench layer disposed over a crystalline substrate are described. In some embodiments, an interfacial layer is disposed over a silicon substrate surface. The interfacial layer facilitates growth of the elevated structure from a bottom of the trench at growth temperatures that may otherwise degrade the substrate surface and induce more defects in the elevated structure. The trench layer may be disposed over the interfacial layer with a trench bottom exposing a portion of the interfacial layer. Arbitrarily large merged crystal structures having low defect density surfaces may be overgrown from the trenches. Devices, such as III-N transistors, may be further formed on the raised crystalline structures while silicon-based devices (e.g., transistors) may be formed in other regions of the silicon substrate.

Abstract: A single fin or a pair of co-integrated n- and p-type single crystal electronic device fins are epitaxially grown from a substrate surface at a bottom of one or a pair of trenches formed between shallow trench isolation (STI) regions. The fin or fins are patterned and the STI regions are etched to form a height of the fin or fins extending above etched top surfaces of the STI regions. The fin heights may be at least 1.5 times their width. The exposed sidewall surfaces and a top surface of each fin is epitaxially clad with one or more conformal epitaxial materials to form device layers on the fin. Prior to growing the fins, a blanket buffer epitaxial material may be grown from the substrate surface; and the fins grown in STI trenches formed above the blanket layer. Such formation of fins reduces defects from material interface lattice mismatches.
