| Zusammenfassung: | Provided is a semiconductor device in which on-resistance is largely reduced based on a new principle of operation. In the semiconductor device, if an embedded electrode is at negative potential, a depletion layer is formed from a trench to a neighboring trench so that a channel is turned off. If the embedded electrode is at a positive potential, the depletion layer is not formed in every region between the neighboring trenches so that the channel is turned on. |
