Patent ID: 7192814

Claim:
A method of forming a semiconductor device comprising: providing a substrate of a first conductivity type having a first surface; forming a first source region and a second source region of the first conductivity type on at least a first portion of the first surface of the substrate wherein the second source region is spaced apart from the first source region; forming a gate structure overlying the first surface of the substrate with a first end of the gate structure overlying an edge of the first source region and a second end of the gate structure overlying an edge of the second source region wherein a first surface of the gate structure is substantially parallel to the first surface of the substrate and faces away from the first surface of the substrate; forming an opening in the gate structure and overlying a second portion of the substrate that is positioned in between the first source region and the second source region; forming an insulator at least on sidewalls of the opening; and forming a conductor within the opening and on the insulator wherein the conductor is not on the underlying substrate.
