Patent ID: 8785987

Claim:
An IGFET device comprising: a substrate; two field oxide regions defined in the substrate and defining a device region therebetween; a source region defined in the substrate within the device region; a drain region also defined in the substrate within the device region and spaced from the source region by a channel region; a first dielectric layer disposed on the substrate within a span of the device region; an active gate insulated from the channel region by the first dielectric layer; a dummy gate disposed on the first dielectric layer; and a second dielectric material insulating the active gate from the dummy gate, the second dielectric material completely covering an entire top surface of the dummy gate, and the second dielectric material including an opening disposed therethrough to the active gate, the second dielectric material extending uninterrupted from the active gate to the dummy gate; and wherein the dummy gate, the active gate, and the second dielectric material disposed therebetween define a capacitor.
