    摘要: A semiconductor structure is disclosed. The semiconductor structure includes a first layer. A second layer is disposed on the first layer and different from the first layer in composition. An interface is between the first layer and the second layer. A third layer is disposed on the second layer. A gate is disposed on the third layer. A source feature and a drain feature are disposed on opposite sides of the gate. Each of the source feature and the drain feature includes a corresponding metal feature at least partially embedded in the second and the third layer. A corresponding intermetallic compound underlies each metal feature. Each intermetallic compound contacts a carrier channel located at the interface.

    摘要: The present disclosure relates to an enhancement mode gallium nitride (GaN) transistor device. The GaN transistor device has an electron supply layer located on top of a GaN layer. An etch stop layer (e.g., AlN) is disposed above the electron supply layer. A gate structure is formed on top of the etch stop layer, such that the bottom surface of the gate structure is located vertically above the etch stop layer. The position of etch stop layer in the GaN transistor device stack allows it to both enhance gate definition during processing (e.g., selective etching of the gate structure located on top of the AlN layer) and to act as a gate insulator that reduces gate leakage of the GaN transistor device.
