| 1. A stacked storage capacitor structure for a LTPS TFT-LCD, comprising:
a substrate;
a first storage capacitor comprising a first conductive layer, a second conductive layer and a first insulating layer therebetween,
wherein the second conductive layer is disposed over the first conductive layer, and wherein the first storage capacitor is
disposed over the substrate;
a third conductive layer comprising a first portion and an extended second portion; and
a second storage capacitor comprising the second conductive layer, the extended second portion of the third conductive layer
and a second insulating layer therebetween, wherein the extended second portion of the third conductive layer is disposed
over the second conductive layer, and wherein the second storage capacitor is over the first storage capacitor, and is electrically
connected thereto; and
a third insulating layer between the second conductive layer and the extended second portion of the third conductive layer,
wherein the first portion of the third conductive layer is electrically connected to the first conductive layer through the
third insulating layer, the second insulating layer and the first insulating layer.
