Abstract: A capacitor for use in relatively high voltage environments is provided. During formation, anodization may be carried out in a manner so that the dielectric layer possesses a relatively thick portion that overlies an external surface of the anode and a relatively thin portion that overlies an interior surface of the anode. In addition to employing a dielectric layer with a differential thickness, the solid electrolyte is also formed from the combination of pre-polymerized conductive polymer particles and a hydroxy-functional nonionic polymer.

Abstract: Non-polar tantalum capacitors and non-polar tantalum capacitor arrays with compact designs are provided. The reduced volume and footprint of the capacitors and arrays in turn reduces the amount of space required in any device in which they are used. In addition, the cost of materials is reduced, and the manufacturing is simplified. Some embodiments of the present invention provide an electromechanical connector between the anode rods of each pair of polar tantalum capacitors, and insulation between the remainder of the capacitor bodies, thus providing a non-polar tantalum capacitor. These non-polar capacitors are mechanically connected to make a non-polar tantalum capacitor array. Other embodiments of the present invention provide for physically connecting the anode rods of the polar capacitors. An insulating encapsulant around the connected rods and between the polar capacitor bodies also holds the capacitors and capacitor arrays together. Additional embodiments of the invention provide an insulating shell in which the polar capacitors are placed, combined with electrical connection and encapsulation of the anode rods.

TL;DR: In this article, a storage capacitor structure comprising a first capacitor electrode on a substrate, a capacitor dielectric layer on the first capacitance electrode and a second capacitor electrode, a pixel electrode layer and a passivation layer was proposed.
Abstract: A storage capacitor structure comprising a first capacitor electrode on a substrate, a capacitor dielectric layer on the first capacitor electrode and a second capacitor electrode on the capacitor dielectric layer, a passivation layer on the second capacitor electrode and a pixel electrode layer on the passivation layer. The second capacitor electrode has an area smaller than the first capacitor electrode. The passivation layer has an opening that exposes a portion of the second capacitor electrode. The pixel electrode layer and the second capacitor electrode are electrically connected through the opening in the passivation layer.
