Abstract
A semiconductor device includes a region of semiconductor material comprising a shielded-gate trench structure. The shielded-gate trench structure includes an active trench, an insulated shield electrode in the lower portion of the active trench, an insulated gate electrode adjacent to the gate dielectric in an upper portion of the active trench, and an inter-pad dielectric (IPD) interposed between the gate electrode and the shield electrode. A conductive region is within the active trench and extends through the gate electrode and the IPD and connected to the shield electrode. The conductive region is electrically isolated from the gate electrode. The gate electrode comprises a shape that is uninterrupted on at least one side of the conductive region in a top view.
