  • Publication number: 20100258810
    Abstract: A method for fabricating a pixel unit is provided. A TFT is formed on a substrate. A protection layer and a patterned photoresist layer are sequentially formed on the substrate entirely. A patterned protection layer is formed by using the patterned photoresist layer as a mask and partially removing the protection layer, wherein the patterned protection layer has an undercut located at a sidewall thereof. A pixel electrode material layer is formed to cover the substrate, the TFT and the patterned photoresist layer, wherein the electrode material layer is disconnected at the undercut and exposes the undercut. A pixel electrode electrically connected to the TFT is formed by lifting off the patterned photoresist layer and parts of the electrode material layer covering the patterned photoresist layer simultaneously through a stripper, wherein the stripper permeates from the undercut to an interface of the patterned photoresist layer and the patterned protection layer.

  • Publication number: 20100237465
    Abstract: A device comprises a substrate (22); a first MiM capacitor (10,20,11) disposed over the substrate; and a second MiM capacitor (10?,20?,11) disposed over the first MiM capacitor. The first MiM capacitor and the second MiM capacitor are electrically connected in parallel. The two MiM capacitors are vertically stacked one above the other. Each MiM capacitor comprises an interconnection layer (10,10?) of the CMOS process as one plate and a thinner conductive layer (11,11?) as the second plate, with an insulating layer (20,20?) disposed therebetween. This allows each MiM capacitor to be formed between two CMOS process interconnection layers. The second plate of the second MiM capacitor is substantially co-extensive with the second plate of the first MiM capacitor, and is disposed substantially directly over the second plate of the first MiM capacitor. The same mask may be used to pattern the second plate of the second MiM capacitor and the second plate of the first MiM capacitor.
