IPC: H01L27/115
Filed: 2005-04-28
Abstract: A method for fabricating a semiconductor device is provided to effectively increase the effective area of a dielectric layer formed between a floating gate and a control gate by performing an additional etch-back process. A preliminary buffer layer with a first thickness of 200~1000 angstroms is formed on a substrate(100), including polysilicon. A surface part of the preliminary buffer layer is etched to form a buffer layer having a second thickness of 100~200 angstroms smaller than that of the first thickness. A hard mask pattern is formed on the buffer layer. A part of the buffer layer and a part of the substrate are continuously and anisotropically etched by using the hard mask pattern as an etch mask to form a buffer layer pattern and an isolation trench. The inside of the trench, a gap between buffer layer patterns and a gap between the hard mask patterns are filled with a field insulation pattern. The hard mask pattern and the buffer layer pattern are etched to form an opening having a small lower width as compared with the upper width of the opening. A dielectric layer is formed on the base surface of the opening. A conductive layer pattern is formed on the dielectric layer to fill the opening.

Abstract: 본 발명은 판형상의 고정체에 대하여 가동체를 소정 방향으로 이동 가능하게 유지하는 가이드 장치를 고정체와 가동체의 대향면에 설치한 개폐 장치에 관한 것이다.  고정체나 가동체, 가이드체를 강판 등의 판형상의 것으로 형성할 수 있기 때문에, 전체의 박형화를 도모할 수 있다.  또한, 이것들을 프레스 가공 등의 비교적 간단한 가공으로 제작할 수 있기 때문에, 저렴한 개폐 장치를 제공할 수 있다.  그리고 이 개폐 장치를 이용한 박형 전자 기기를 제공한다.

Title: Pickup tool for die bonding process of thin ic chips
Inventor: LEE JUNG KU
IPC: H01L21/68
Filed: 2005-08-25
Abstract: A pick-up tool for use in a die bonding of a thin plate type IC(Integrated circuit) chip is provided to improve pick-up workability and to preventing deformation of the IC chip by using an improved end of the pick-up tool and a plurality of through holes. A rectangular-type extended inserting unit(21) is formed at an end of a body(20) of a pick-up tool. The rectangular-type extended inserting unit is used for being inserted into a vacuum providing holder of a die bonding. A plurality of through-holes(23,23') are formed, which pass through from a bottom of the body to the rectangular-type extended inserting unit. A rectangular sectional end unit(24) corresponding to an area of an IC chip is formed at a lower of the body. A bottom surface of the rectangular sectional end unit has a flat shape.
