Title: Method for fabricating contact hole of semiconductor device
Inventor: KIM YOU CHANG
IPC: H01L21/28
Filed: 1998-12-28
Abstract: PURPOSE: A method for fabricating a contact hole of a semiconductor device is provided which can increase the etching selectivity of a photoresist film and a silicon layer using a CHF3/CO/O2/Ar mixed gas during an etching process requiring high etching selectivity such as a metal line, and can form a stable and reproducible contact hole. CONSTITUTION: In a process of forming a contact hole by etching a thick oxide like a metal line contact, the contact hole is formed by etching an oxide(14), a nitride and a nitrogen oxide using a CHF3/CO/O2/Ar etching gas by considering not only the etching selectivity of the oxide and a photoresist film but also the nitride and the nitrogen oxide, or in case of thicker oxide than the above oxide, the contact hole is formed by etching the oxide with a C-F gas/CO/O2/Ar mixed gas and then by etching the remained oxide, the nitride and the nitrogen oxide with a CHF3/CO/O2/Ar mixed gas. Thus, the method can improve the stability and the reproducibility, and the process yield and the reliability of the device operation can be improved.

Abstract: 정기적 잉크 주입 가공품(도 2)은 이미지-처리 스테이지부(73)에 도입된 무작위-수 발생기로서의 노즐(82)에 의해 감소된다.  이는 무작위 프로세싱을 통해 초기에 유래된 고정 패턴이 제공되지 않는 것에 사용된다.  보다 정확히 말하면, 시스템은 사실상 무작위 또는 적어도 위무작위를 이미지-처리 스테이지부로 도입한다.  하나의 슈퍼픽셀(87)이 복수의 슈퍼픽셀로부터 무작위로 선택되는 것이 바람직하며, 이러한 슈퍼픽셀은 도트-변위 에러가 가장 두드러진 색조 범위의 일부인 중간 색조 레벨을 가지는 지점에 대해 선택된다.  슈퍼픽셀을 사용하는 이미지 스케일링 또는 기타의 이유를 조정하는 메모리 부재(78)가 없는 경우에는, 무작위-도입 접근법은 이용가능한 프린터 해상도보다 조악한 픽셀 그리드를 이용하는 이미지-데이타 입력부(71)를 준비하는 접점 패드(86)를 포함한다.  선택된 슈퍼픽셀(87)은 프린터 해상도에서 개별적인 픽셀의 세트를 형성하도록 조악한 그리드에서 인가된다.  주요 사양은 후속 프린팅 패스에서의 프린팅에 관한 것이다.  즉, 이미지-처리 스테이지부의 하류에 있는 프린트마스킹 스테이지부(74)는 잉크 주입의 임시활당을 복수의 패스로 설정하는 데 사용된다.  슈퍼픽셀을 이미 채용하는 프린팅 시스템에 대해, 슈퍼픽셀을 무작위로 선택하는 것은 가공품 감소 이득을 달성하면서도, 거의 장치가 복잡해지지 않으며, 프로세싱 시간 및 비용이 부가되지 않는다.

If 3 people, 3 sets(6 cams) are needed. The cams(6) play a role to change the rotary movement of the driving axis into reciprocation of massage belts. This item can be applied to a single user machine whose intensity can be controlled as user's preference and a machine which massages waist, foot, or calf at the same time.1

Title: Novel photoresist containing halogen
Inventor: BAEK GI HO
IPC: G03F7/039
Filed: 1999-08-31
Abstract: PURPOSE: A new photoresist polymer containing halogen is provided for using in lithographic process with VUV in production area of microcircuits for high integrated semiconductor element because of its remarkable etching-resistance, heat-resistance and adhesiveness and substantially little having absorbancy at the wavelength of 193 to 157nm. CONSTITUTION: A novel photoresist polymer containing halogen is featured by its performance at a light source of 157nm. The polymer can be prepared by comprising a photoresist monomer such as 5-norbonene-2-hydroxymethylethylbutyl carboxylate-3-carboxylic acid or diacrylate compound. The polymer can also include another compound of a formula 3 as a second monomer to reduce light absorbancy at 157nm. The second monomer compound preferably contains halogen element such as fluorine. In formula, U represents H, F, Cl, Br, I, CH3 or CF3.

Abstract: PURPOSE: A bathtub for a public bath is provided to maximize an efficiency of a hot water bath, to absorb and eliminate a bad smell of bath water, and to improve sterilizing power by using a far infrared ray of a charcoal. CONSTITUTION: A bathtub for a public bath comprises:a bathtub(100) containing a waterproof course(111) formed on the surface of a bottom layer(110), a mortar(112) formed on the top surface of the waterproof course, and a finishing material(122) adhered on the surfaces of side walls(120); a charcoal column layer(113) formed inside of the side walls; and a finishing material(114) formed on the upper surface of the charcoal column layer.
