Zusammenfassung: | A semiconductor device includes a semiconductor substrate, a doped zone, a polysilicon layer and an elongate plug structure. The doped zone is within the semiconductor substrate. The polysilicon layer is disposed in a trench electrically isolated from the semiconductor substrate by an insulating layer. The elongate plug structure extends in a lateral direction in or above the semiconductor substrate. The elongate plug structure provides electrical connection between the doped zone and the polysilicon layer. |
