Abstract:
1. A semiconductor device comprising: a substrate, and a device isolation layer of electrically insulating material disposed at an upper portion of the substrate and delimiting an active region of the substrate; a gate electrode extending across the active region such that a first section of the active region lies to one side of the gate electrode and a second section of the active region lies to the other side of the gate electrode, the gate electrode having a linear main section extending longitudinally across the active region in a first direction, and at least one first gate tab protruding from the linear main section in a second direction, different from the first direction, toward the first section of the active region, and the first gate tab covering a boundary between the active region and the device isolation layer; a first electrically conductive contact plug disposed on the first section of the active region; and a second electrically conductive contact plug disposed on the second section of the active region, and wherein the first contact plug spans a first width of the active region in the first direction, the second contact plug spans a second width of the second section of the active region in the first direction, and the second width is greater than the first width.
