Abstract
A semiconductor device includes a doped substrate, a barrier layer, a channel layer, a doped semiconductor structure, and the conductive structure. The barrier layer is disposed on the doped substrate. The channel layer is disposed between the doped substrate and the barrier layer, in which a bandgap of the barrier layer is greater than a bandgap of the channel layer. The doped semiconductor structure is embedded in the doped substrate, in which the doped substrate and the doped semiconductor structure have different polarities, so as to form a diode therebetween. The conductive structure is disposed over the doped substrate and makes contact with the doped semiconductor structure, in which the conductive structure extends from the doped semiconductor structure to a position higher than the channel layer and the barrier layer.
