Abstract:
A HEMT device is provided. The HEMT device includes a substrate, a buffer layer, a first epitaxial layer, a second epitaxial layer, an insulating layer, a gate, a source, a drain, a trench, and a metal layer. The buffer layer is formed on the substrate. The first epitaxial layer is formed on the buffer layer. The second epitaxial layer is formed on the first epitaxial layer. The insulating layer is formed on the second epitaxial layer. The gate is disposed in the insulating layer. The source and the drain are disposed in the insulating layer. The trench passes through the insulating layer and the second epitaxial layer, and extends into the first epitaxial layer. The metal layer is formed on the insulating layer to connect to the source, and is filled into the trench to electrically connect to the first epitaxial layer and the source.

Claim (Index 1):
A method for fabricating a high electron mobility transistor (HEMT) device, comprising:\n providing a substrate; forming a buffer layer on the substrate; forming a first epitaxial layer on the buffer layer; forming a second epitaxial layer on the first epitaxial layer; forming an insulating layer on the second epitaxial layer; disposing a gate in the insulating layer; disposing a source and a drain in the insulating layer, wherein the source and the drain are located on both sides of the gate; forming a trench to pass through the insulating layer and the second epitaxial layer, and to extend into the first epitaxial layer; and forming a metal layer on the insulating layer to connect to the source, and to fill into the trench to electrically connect to the first epitaxial layer and the source.
