Title: Flat panel display and manufacturing method thereof
Inventor: LAI HAN-CHUNG
IPC: H01L27/146
Filed: 2003-05-12
Granted: 2004-06-01
Abstract: The present invention provides a flat panel display, whose second metal layer (M2), doped semiconductor layer and semiconductor layer are defined by four etching processes. The first process is wet etching to define the second metal layer by using the first photoresist layer as the mask. The second process is dry etching containing oxygen, in which the first photoresist layer is partly ashed and becomes the second photoresist layer having a channel pattern, and etch doped semiconductor layer and semiconductor layer at the same time. The third process is wet etching to etch the second metal layer by using the second photoresist layer as the mask. The fourth process is dry etching to etch the doped semiconductor layer by using the second photoresist layer as the mask, so as to define the source and drain. The said second metal layer has shrunk edge inward through two wet etching processes. The doped semiconductor layer has shrunk edge inward through a dry etching process containing oxygen until its edge is the same as the second metal layer after the first etching. Thus, the distance between the edge of the second metal layer and the edge of the semiconductor layer is decreased.

Granted: 2007-06-11
Abstract: A cholesteric liquid crystal has the features of high brightness, high contrast, low power consumption, the ability of memory, wide viewing angle, and flicker-free. However, the bandwidths of the cholesteric liquid crystal depend on the range of the pitch of the cholesteric liquid crystal. If the range of the pitch is too narrow to make the bandwidths include the bandwidths of the visible light, the cholesteric liquid crystal does not display true color. In the present invention, the method of broadening a reflection band of a cholesteric liquid crystal is provided, that the cholesteric liquid crystal comprises cholesteric liquid crystals made of unpolymerized nematic liquid crystals and unpolymerized chiral agents, and chiral monomers or liquid crystal monomers. The cholesteric liquid crystal may comprises liquid crystal materials and chiral materials, wherein one of which has active double bounds and the other does not have active double bounds. The cholesteric liquid crystal has wide range of pitch by means of the interference of light sources and so the purpose of broadening bandwidths of the cholesteric liquid crystal is achieved.

Title: Microwave remediation technology for heavy metal contaminated soil
Inventor: CHANG KUEN-SEN
Filed: 2003-07-10
Granted: 2007-02-01
Abstract: An innovative microwave remediation, not microwave solidification/stabilization, for heavy metal contaminated soil had been developed. Three steps/mechanisms were shown as follows. First, hydrogen ions, which came from the adding of low concentration of acid, were completely mixed with contaminated soil by shaking and then transferred to the bulk film of soil. Second, iron material was inserted into the mixture of acid-contaminated soil. Open system microwave extraction, not closed-vessel system, was carried out in an output range of medium or high power. Unsteady electrons and local high temperature were generated since iron material excited, which caused heavy metal releasing from soil surface. Third, soil sample was shaken again for ensuring complete removal of heavy metal. A goal of background soil was expected via this innovative remediation technology not only in the effective metal content but also in the total metal content.
