Granted: 2007-08-21
Abstract: A liquid crystal display (LCD) system 200 having LED backlight luminance sensing is disclosed. An array of LEDs in a backlighting position includes a plurality of LED stings 208. At least one LED from at least one string is identified as a sampling LED 202. The light emitted from the sampling LED is detected via an optical path using a light sensor 210. The reading from the sensor is contrast with a command, which results in a power compensation to the array accordingly. In one embodiment, the system includes a sampling enclosure 204 encasing the sampling LED 202 and light sensor 210. The sampling LED's direction of emission is altered from the string and reflected from the inside of the enclosure. In another embodiment, the system includes a direct sensing optical path between the light sensor 610 and the sampling LED 602.

Title: Semiconductor device and process
Inventor: OIKAWA MAKOTO
IPC: H01L29/10
Filed: 2002-09-11
Granted: 2006-12-21
Abstract: This invention provides a semiconductor device and process, to eliminate the deterioration of electrical insulation between the drain and the source (or between the collector and the emitter) of a power-MOSFET, which is often created by a field concentration at the bottom of the gate electrode of the most outer periphery of a real acting region in a conventional device. At the most outer periphery of the real acting region a trench having a shallower depth than the other trench in the real acting region is formed. With such arrangement the field concentration at the bottom of the gate electrode in the most outer periphery of the real acting region can be reduced, and the deterioration of the electrical insulation between the drain and the source (or between the collector and the emitter) can be controlled. Moreover, by forming a narrower trench opening at the most outer periphery of the real acting region, trenches of varying depth can be formed in a same one process.

Title: AlGaInP light emitting diode
Inventor: CHEN NAI-CHUAN
IPC: H01L33/00
Filed: 2002-10-17
Granted: 2003-11-01
Abstract: An AlGaInP light emitting diode with improved illumination is provided. The AlGaInP light emitting diode includes a semiconductor substrate, a light re-emitting layer, an AlGaInP layer with a first doping concentration, an AlGaInP lower cladding layer with a second doping concentration less than the first doping concentration, an undoped AlGaInP active layer, an AlGaInP upper cladding layer, a window layer, an annular-shaped top electrode on the window layer and a layered electrode on a bottom of the semiconductor substrate. The light re-emitting layer includes at least a first region formed of the light re-emitting layer and a second region formed of Al2O3 enclosing the first region. Since AlGaInP layer between the AlGaInP lower cladding layer and the light re-emitting layer has the first doping concentration larger than that of the AlGaInP lower cladding layer, the AlGaInP layer provides a transverse current spreading. The Al2O3 layer also improves light reflection illuminating on the light re-emitting layer. As a result, the brightness performance of the light emitting diode is improved.

Granted: 2004-10-21
Abstract: The present invention discloses a multi-bits memory cell device. Its manufacturing method is first to provide a semiconductor substrate on which a gate dielectric layer, a polysilicon layer and the first patterned photoresist layer have been formed. The first patterned photoresist is used as etching masks to etch away portions of the polysilicon layer and form the gate electrodes. After removing the dielectric portion on the substrate surface, a conformal oxide dielectric layer is formed onto the gates and substrate. Another conformal insulating layer is then formed on the oxide layer. The third layer of oxide dielectric layer is formed onto the insulating layer. The tri-layer spacers are formed at the side-walls of the gates with oxides after etching these oxide/insulator/oxide layers. The semiconductor substrate is then implanted to form the source and drain regions with the gates and tri-layer spacers as implantation masks on the substrate. Finally, the top portions of gates and source/drain regions are exposed and reacted with metals to form silicides after removing the oxides on the surface of the substrate.
