Patent ID: 8158477

Claim:
A method for forming a pixel of an electroluminescence device, comprising: providing a substrate; defining at least a first area for capacitors and a second area for a transistor on the substrate; forming a first conductive layer over the first area; forming a first dielectric layer over the first conductive layer over the first area; forming a second conductive layer over the first dielectric layer over the first area; forming a second dielectric layer over the second conductive layer over the first area; forming a third conductive layer over the second dielectric layer over the first area; forming a layer of capping silicon nitride between the second dielectric layer and the third conductive layer over the first area; forming a semiconductor layer over the second area; forming a gate oxide layer over the second area; and forming a fourth conductive layer over the gate oxide layer over the second area; wherein the first conductive layer over the first area is directly connected to a power supply voltage, wherein the second conductive layer is electrically connected to the fourth conductive layer, and wherein the first conductive layer, the first dielectric layer, and the second conductive layer over the first area collectively form a first one of the capacitors over the first area, the second conductive layer, the second dielectric layer, and the third conductive layer over the first area collectively form a second one of the capacitors over the first area, and the semiconductor layer, the gate oxide layer, and the fourth conductive layer over the second area collectively form a transistor.
