Abstract
A nitride-based semiconductor device includes a substrate, a buffer, a first nitride-based semiconductor layer, a second nitride-based semiconductor layer, a S/D electrode, a second S/D electrode, and a gate electrode. The buffer is disposed over the substrate and includes at least one layer of a nitride-based semiconductor compound doped with an acceptor at a top-most portion of the buffer. The first and second nitride-based semiconductor layers are disposed over the buffer. The first S/D electrode is disposed over the second nitride-based semiconductor layer, in which the first S/D electrode extends downward to a position lower than the first nitride-based semiconductor layer, so as to form at least one first interface with the top-most portion of the buffer, making contact with the at least one layer of the nitride-based semiconductor compound. The second S/D electrode and the gate electrode are disposed over the second nitride-based semiconductor layer.
