Title: A method to form high performance copper damascene interconnects by de-coupling via and metal line filling
Inventor: CHA CHER LIANG
IPC: H01L23/532
Filed: 2001-08-14
Granted: 2002-09-11
Abstract: A method to form robust dual damascene interconnects by de-coupling via and connective line trench filling has been achieved. A first dielectric layer is deposited overlying a silicon nitride layer. A shielding layer is deposited. The shielding layer, the first dielectric layer, and the silicon nitride layer are patterned to form via trenches. A first barrier layer is deposited to line the trenches. The via trenches are filled with a first copper layer by a single deposition or by depositing a seed layer and then electroless or electrochemical plating. The first copper layer is polished down to complete the vias. A second barrier layer is deposited. The second barrier layer is patterned to form via caps. A second dielectric layer is deposited. A capping layer is deposited. The capping layer and the second dielectric layer are patterned to form connective line trenches that expose a part of the via caps. A third barrier layer is deposited to line the connective line trenches. The third barrier layer and the via caps are etched to form trench barrier sidewall spacers and to expose the vias. The connective line trenches are filled with a second copper layer by a single deposition, by a first deposition of a seed layer followed by plating, or by plating using the via as the seed layer. The second copper layer is polished down.

Title: Process for selective hydrogenation of alkynes and catalyst therefor
Inventor: J YONG RYU
IPC: C07C5/00
Filed: 2002-03-20
Granted: 2008-11-01
Abstract: Acetylenic compounds in olefin streams such as mixed 1,3-butadiene were selectively hydrogenated over the supported copper catalysts on highly porous supports such as alumina, silica, etc. The preferred supports have the average pore diameter larger than about 200 Å, no micro pores, total pore volume larger than about 0.65 cc/g, and preferably less than about 230 m<2>/g BET surface area. The copper catalysts were preferably promoted with the Group VIII metal such as palladium to improve low activity of copper catalyst. The product stream typically contains less than 20 ppm total alkynes. Also the copper catalysts and the palladium promoted copper catalysts may be modified with zinc oxide to improve the performance of the catalysts. The reactor was loaded with two or more copper catalysts promoted with different levels of palladium. Preferably the copper catalysts were also modified with silver, gold or both silver and gold to reduce polymer formation by the copper component of the catalyst, improve the yield of olefins such as 1,3-butadiene, and prevent the loss of copper and/or palladium due to leaching out into the liquid phase of hydrocarbon.

Title: Adapted pre-filtering for bit-line repeat algorithm
Inventor: WEITBRUCH SEBASTIEN
IPC: G09G3/28
Filed: 2002-04-11
Granted: 2003-09-11
Abstract: When the observation point on a PDP screen moves, artefacts will be introduced which are commonly described as ""dynamic false contour"". A simple way to reduce this effect requires the use of more sub-fields at the expense of panel brightness. A first idea called Bit-Line-Repeat (BLR) makes it possible to exchange vertical resolution with addressing time in order to dispose of more sub-fields for the same brightness. Nevertheless, such a solution introduces some vertical artefacts mostly during movement. Therefore, before the step of sub-field encoding a vertically filtering of the picture divided into pixel blocks is performed, wherein each block includes at least one pixel in horizontal direction and a number of pixels corresponding to the number of common lines in vertical direction. The effect of the pre-filtering step is that the difference of brightness values within each pixel block is limited to a predetermined value. In that case the BLR introduces only a slight vertical loss free from motion artefacts.

Title: A method and of manufacture for tri-color white LED
Inventor: CHEN HSING
IPC: H01L33/50
Filed: 2002-06-07
Granted: 2003-11-21
Abstract: One of the manufacturing methods of white LED in the prior art is to add YAG yellow phosphor powder into blue LED die, there is only two wavelengths of white light, so it can only be applied in pointer and cannot be actually applied in illumination. The other one of the manufacturing methods is to use ultraviolet light to excite the tri-color phosphor powder to generate tri-color white light, since the decay time of ultraviolet LED die is very short, and there is no transparent resin solely for ultraviolet packaging, its lifetime and quality are quite depressed. The manufacturing method of tri-color white LED of the present invention is to choose a blue LED die with wavelength between 420nm and 475nm; coat red, green phosphor bodies on the die; excite red, green phosphor bodies by blue light to generate white light with three wavelengths of red, blue, green. It is the best choice to fabricate the white LED with a single die for generating high-luminance tri-wavelength.
