Title: N-hydroxy-2-(alkyl, aryl, or heteroaryl sulfanyl, sulfinyl or sulfonyl)-3-substituted alkyl, aryl or heteroarylamides as matrix metalloproteinase inhibitors
Inventor: VENKATESAN ARANAPAKAM MUDUMBAI
IPC: C07D307/30
Filed: 1998-03-17
Granted: 2004-01-01
Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-alpha converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-alpha from membrane bound TNF-alpha precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states. The present invention provides low molecular weight, non-peptide inhibitors of matrix metalloproteinases (MMPs) and TNF-alpha converting enzyme (TACE) for the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, diabetes (insulin resistance) and HIV infection.

Title: Method of forming tungsten pattern of semiconductor device
Inventor: HAHM JIN-HWAN
IPC: H01L21/3205
Filed: 1998-06-22
Granted: 2001-03-11
Abstract: There is provided a method of forming a tungsten film pattern which is used as a bit line in a semiconductor device and has a design rule of 0.34 mu m or less. In this method, a capping layer being a titanium nitride having a lower etch rate than a tungsten film is formed between the tungsten film and a photoresist film. After a photoresist pattern is formed by exposing and developing the photoresist film, the tungsten film is patterned by a dry etch method. Here, the capping film serves as a hard mask for lowering the reflectivity of the tungsten film and generating a polymer when etching the tungsten film. Thus, patterning failures can be prevented. A titanium nitride or aluminum film having a lower etch rate than the tungsten film can be used as the capping film, and an anti reflective layer such as a silicon oxynitride layer is added on the capping film. The capping film serves as a hard mask during the tungsten film etch process, to prevent patterning failures such as damage to an anti reflective pattern and the photoresist pattern.

Title: Integrated circuits with wells
Inventor: LI LI-CHUN
IPC: H01L27/108
Filed: 1998-08-24
Granted: 2001-06-07
Abstract: Dynamic random access memory (DRAM) cells are formed in a P well formed in a biased deep N well (DNW). PMOS transistors are formed in N wells. The NMOS channels stop implant mask is modified not to be a reverse of the N well mask in order to block the channels stop implant from an N+ contact region used for DNW biasing. In DRAMs and other integrated circuits, a minimal spacing requirement between a well of an integrated circuit on the one hand and adjacent circuitry on the other hand is eliminated by laying out the adjacent circuitry so that the well is located adjacent to a transistor having an electrode connected to the same voltage as the voltage that biases the well. For example, in DRAMs, the minimal spacing requirement between the DNW and the read/write circuitry is eliminated by locating the DNW next to a transistor precharging the bit lines before memory accesses. One electrode of the transistor is connected to a precharge voltage. This electrode overlaps the DNW which is biased to the same precharge voltage. This electrode provides the DNW N+ contact region.

Title: Encoding method
Inventor: WANG SHIDE
IPC: G06F3/01
Filed: 2000-02-24
Granted: 2003-06-01
Abstract: In a method of encoding a Pinyin string, each of the letters of the Pinyin string is represented by five bits. The final tone digit, which can be in the range of 1 to 5, is also represented by five bits, unless the Pinyin string contains six letters. In Pinyin strings containing the maximum of six letters, the tone digit '5' is never used, so that in this case the final tone digit is represented by only two bits. Therefore, any valid Pinyin string can be represented by a 32-bit word, which can be efficiently stored and compared with other Pinyin strings. The method is particularly suitable for compact, low power text storage and/or messaging devices.
