Granted: 2006-03-21
Abstract: To prevent display failures due to a lateral electric field occurring between pixel electrodes in a liquid crystal device having a flattened interlayer insulating film and to make a high-quality image display possible. The liquid crystal device has a liquid crystal layer 50 held between a counter substrate 30 and a TFT array substrate 200 on which a plurality of pixel electrodes 9a are arranged in a matrix. The TFT array substrate 200 is formed by successively laminating a semiconductor layer 1, gate insulating film 2, scanning line 3 and capacitor line 3b, flattened interlayer insulating film 4, interlayer insulating film 7 and pixel electrodes 9a on a substrate 10. A pattern film 6b is arranged between the interlayer insulating film 4 and the interlayer insulating film 7 approximately according to the region between adjacent pixel electrodes 9a. By arranging the pattern film 6b, the surface level differs on the side of the TFT array substrate 200 in contact with the liquid crystal layer 50, and this prevents alignment failures in the liquid crystal molecules due to a lateral electric field occurring between adjacent pixel electrodes.

Title: Method and device for manufacturing steel wire balls woven by stainless steel
Inventor: LIN CHUEN-DUNG
IPC: B21F45/00
Filed: 2000-10-17
Granted: 2001-09-21
Abstract: This invention is related to a method and device for manufacturing steel wire balls woven by stainless steel, comprising the steps of: (a) rolling to curl a metal wire; (b) using gears to rotate and to wind the metal wire; and (c) and forming the steel wire balls. The metal wire is pressed into a flat configuration by a first roller set. A second roller set pulls another end of the metal wire. A scraper located between two roller sets then scraps the flat metal wire to generate stress deviations along the surface of the metal wire so as to form a curled, helical configuration. The curled metal wire then passes through an L-shaped tube adhered to a gear set and then is drawn out from the lower end of the L-shaped tube. The L-shaped tube is constantly kept to a state where the vertical tube opening faces upwards while rotating along the gear set so as to gradually cause the metal wire to wind about a core material. The wound metal wire winds about the minor axis of the core material along a radial direction so as to be consistent with the radial direction of the core material, such that the all intersects of the metal wire are concentrated at the apexes of the minor axis of the core material, without affecting the flexibility of the remaining locations of the steel wire ball. As such, a steel wire ball that has excellent flexibility, provides gripping comfort, and prevents the metal wire from detaching, can be obtained.

Title: Charge pump system having multiple independently activated charge pumps and corresponding method
Inventor: HSU LOUIS L C
IPC: H02M3/07
Filed: 2001-05-08
Granted: 2004-03-11
Abstract: A charge pump generator system and method is provided which more precisely maintains the level of an internally generated voltage supply by operating some or all of the available charge pumps depending upon the voltage level reached by the voltage supply. When the voltage supply is far from its target level, a first group and a second group of charge pumps are operated. The first group may preferably have a faster pumping rate or a greater number of charge pumps than the second group. When the voltage supply exceeds a first predetermined level, the first group of charge pumps is switched off while the second group remains on, such that the rate of charge transfer slows. The second group continues operating until a second, e.g. target, voltage level is exceeded. The slower rate of charge transfer then effective reduces overshoot, ringing and noise coupled onto the voltage supply line. Preferably, at least one charge pump operates in both standby and active modes, thereby reducing chip area.

Filed: 2001-07-13
Granted: 2003-03-21
Abstract: A plurality of discharge electrodes having transparent electrodes connected to bus electrodes are arranged on the inner side of a front substrate. Alternatively, discharge electrodes having transparent electrodes and capable of discharging between their respective neighboring electrodes on both sides are arranged on the inner side of the front substrate. The front substrate is provided on the side of the display surface where discharge-generated light radiates out to the exterior. Shielding parts for shielding incident light from the exterior are formed on the transparent electrodes, or along the front substrate. Accordingly, the shielding parts reduce the surface reflection to improve the bright room contrast ratio. Forming the shielding parts with the same material as that of the bus electrodes prevents fabrication processes from becoming complicated. The areas of the shielding parts can be varied with the luminescent colors of cells, to change the luminescent brightness by the cell.

Title: Electrochemical methods for folishing copper films on semiconductor substrates
Inventor: ZHU MEI
IPC: C25D5/18
Filed: 2002-01-16
Granted: 2003-05-21
Abstract: Methods for electrochemically polishing copper films on semiconductor substrates use an alkaline solution with a pH in the range of about 8.0 to 10.5. A constant current density of from 5 to 100 amperes per square foot is applied to an electrochemical cell formed by an electrode, the alkaline solution and the copper film. Copper is removed at a rate of from 500 to 10,000 angstroms per minute. The end point for the electro-polishing is detected by a sudden change in applied voltage. The alkaline polishing solution may also contain copper ions so that when the current direction is reversed, copper is deposited onto the copper film. Furthermore, this copper deposition will occur selectively on the exposed copper surface but not on the exposed barrier layer surface. Hence, the method can compensate for dishing and erosion by re-depositing copper in regions after too much copper was removed from those regions.
