Abstract
A high electron mobility transistor includes a first III-V compound layer. A second III-V compound layer is disposed on the first III-V compound layer, wherein the composition of the first III-V compound layer and the second III-V compound layer are different from each other. A source electrode and a drain electrode are disposed on the second III-V compound layer. A gate electrode is disposed on the second III-V compound layer between the source electrode and the drain electrode. An insulating layer is disposed between the drain electrode and the gate electrode and covering the second III-V compound layer. Numerous electrodes are disposed on the insulating layer and contact the insulating layer, wherein the electrodes are positioned between the gate electrode and the drain electrode and a distribution of the electrodes decreases along a direction toward the gate electrode.
