High Electron Mobility Transistor and Method of Forming the Same |
| 摘要 |
A High Electron Mobility Transistor (HEMT) includes a first III-V compound layer having a first band gap, and a second III-V compound layer having a second band gap over the first III-V compound layer. The second band gap is smaller than the first band gap. The HEMT further includes a third III-V compound layer having a third band gap over the second III-V compound layer, wherein the third band gap is greater than the first band gap. A gate electrode is formed over the third III-V compound layer. A source region and a drain region are over the third III-V compound layer and on opposite sides of the gate electrode. |

1. A High Electron Mobility Transistor (HEMT) comprising:
a first III-V compound layer; a second III-V compound layer over the first III-V compound layer; a third III-V compound layer over the second III-V compound layer, wherein the first III-V compound layer, the second III-V compound layer, and the third III-V compound layer are configured so that a Two-Dimensional Electron Gas (2DEG) is formed in the second III-V compound layer and close to an interface between the second III-V compound layer and the third III-V compound layer; a gate electrode over the third III-V compound layer; and a source region and a drain region over the third III-V compound layer and on opposite sides of the gate electrode. |
