Patent ID: 6908833

Claim:
A method of forming a semiconductor electrical device, comprising: forming an insulating layer on a substrate, wherein the insulating layer inhibits the flow of electricity, the insulating layer having a top surface and a bottom surface, wherein the bottom surface is proximate to the substrate, and the top surface is separated from the bottom surface by a first distance; implanting silicon atoms into the insulating layer to form a first region of silicon atoms, wherein the first region extends from the top surface to the bottom surface of the insulating layer, and wherein the region has a first width; and implanting silicon atoms into the insulating layer to form a second region of silicon atoms, where the second region extends from the top surface of the insulating layer to a second distance, which is less than the first distance separating the top and the bottom of the insulating layer, and wherein the second region has a width which is greater than the first width.
