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 gate oxide layer over the first area; forming a first conductive layer over the gate oxide 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 capping nitride on the second dielectric layer, wherein the capping nitride has an opening to expose a portion of the second dielectric layer over the second conductive layer; forming an organic layer over the capping nitride to contact the second dielectric layer via the opening of the capping nitride; forming a third conductive layer over the organic layer over the first area, forming a semiconductor layer over the second area without over the first area; forming a gate oxide layer contacting with the substrate over the first area; forming a fourth conductive layer over the gate oxide layer over the second area; wherein the first conductive layer over the first area is connectable to a power supply voltage, 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 directly over the second conductive layer, the organic layer directly over the second dielectric layer, and the third conductive layer, which is directly over the organic 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, and wherein the gate oxide layer in the first area is formed directly on the substrate; and forming a seventh conductive layer contacting the semiconductor layer, wherein the seventh conductive layer is formed of the same conductive film as the second conductive layer.
