Abstract
The present disclosure relates to semiconductor power devices, and in particular, to a high-electron-mobility transistor (HEMT) with high voltage endurance capability and a preparation method thereof. The high-electron-mobility transistor with high voltage endurance capability includes a gate electrode, a source electrode, a drain electrode, a barrier layer, a P-type nitride semiconductor layer and a substrate, wherein the P-type nitride semiconductor layer is between the barrier layer and the substrate, which is insufficient to significantly deplete a two-dimensional electron gas in a channel except a gate stack, the source electrode is in electrical contact with the P-type nitride semiconductor layer, and the source electrode and the drain electrode are both in electrical contact with the two-dimensional electron gas.
