Abstract: Methods for manufacturing semiconductor wafer structures are described which exhibit improved lifetime and reliability. The methods comprise transferring an active semiconductor layer structure from a native non-lattice-matched semiconductor growth substrate to a working substrate, wherein strain-matching layers, and optionally a portion of the active semiconductor layer structure, are removed. In certain embodiment, the process of attaching the active semiconductor layer structure to the working substrate includes annealing at an elevated temperature for a specified time.

Abstract: A high voltage and high power gallium nitride (GaN) transistor structure is disclosed. A plurality of structural epitaxial layers including a GaN buffer layer is deposited on a substrate. A GaN termination layer is deposited on the plurality of structural epitaxial layers. The GaN termination layer is adapted to protect the plurality of structural epitaxial layers from surface reactions. The GaN termination layer is sufficiently thin to allow electrons to tunnel through the GaN termination layer. Electrical contacts are deposited on the GaN termination layer, thereby forming a high electron mobility transistor.
