Abstract
A semiconductor device is provided. The semiconductor device includes a n− type layer disposed at a first surface of a n+ type silicon carbide substrate and a trench disposed at the n− type layer. Additionally, a first gate electrode and a second gate electrode are disposed in the trench and separated from each other. A source electrode is insulated from the first gate electrode and the second gate electrode. Further, the semiconductor includes a drain electrode that is disposed at a second surface of the n+ type silicon carbide substrate, a first channel disposed adjacent to a side surface of the trench and a second channel disposed under the lower surface of the trench. The first channel and the second channel are separated from each other.
