Abstract:
1. A semiconductor device comprising: a substrate of a first conductivity type having a first surface; a first source region of the first conductivity type on the first surface of the substrate; a second source region of the first conductivity type on the first surface of the substrate wherein the second source region is spaced apart from the first source region; a gate structure overlying the first surface of the substrate, the gate structure having a first end overlying an edge of the first source region, a second end overlying an edge of the second source region, the gate structure having a first surface substantially parallel to the first surface of the substrate and facing away from the first surface of the substrate; an opening extending from the first surface of the gate structure into the gate structure including the opening having sidewalls; an insulator on at least sidewalls of the opening; and a conductor abutting the insulator and within the opening wherein the conductor does not overlie the first region or the second source region.
