| 20120205773 | SCHOTTKY DIODE WITH LOWERED FORWARD VOLTAGE DROP - A Schottky diode with a lowered forward voltage drop has an N− type doped drift layer formed on an N+ type doped layer. The N− type doped drift layer has a surface formed with a protection ring inside which is a P-type doped layer. The surface of the N− type doped drift layer is further formed with an oxide layer and a metal layer. The contact region between the metal layer and the N− type doped drift layer within the P-type doped layer forms a Schottky barrier. An upward extending N type doped layer is formed on the N+ type doped layer and under the Schottky barrier to reduce the thickness of the N− type doped drift layer under the Schottky barrier. This lowers the forward voltage drop of the Schottky diode. | 08-16-2012 |

| 20100039597 | Liquid Crystal Display Panel and Method for Manufacturing Thereof and Liquid Crystal Display Incorporating the Same - A liquid crystal display panel including several first electrode portions, several second electrode portions, and a smectic liquid crystal layer is provided. The first electrode portions and the second electrode portions are disposed on a first substrate. When an AC voltage is applied on the first electrode portions and the second electrode portions, the direction of a horizontal electrical field formed between each first electrode portion and the adjacent second electrode portion is parallel to the surface of the first substrate. The smectic liquid crystal layer is interposed between the first substrate and a second substrate. During the phase change of a liquid crystal molecule of the smectic liquid crystal layer, the horizontal electrical field generated by applying the AC voltage on the first electrode portions and the second electrode portions facilitates the alignment of the liquid crystal molecule of the smectic liquid crystal layer. | 02-18-2010 |
