Abstract:
A semiconductor device and a forming method thereof are provided to weaken a dielectric breakdown effect dependent on a time in a state of mis-alignment of a via contact. A first interlayer dielectric(110) having a trench is formed on a semiconductor substrate(100). A mask pattern is formed on the first interlayer dielectric. The trench is filled with a first conductive pattern(118). A second interlayer dielectric(112a) includes an opening for exposing the first conductive pattern formed on the mask pattern. The opening is filled with a second conductive pattern(126f). The second conductive pattern is connected to the first conductive pattern. The mask pattern has etch selectivity to the second interlayer dielectric. The trench penetrates the mask pattern.
Abstract:
A method for forming a fuse and a pad in a semiconductor device is provided to simplify a manufacturing process by forming simultaneously openings at a fuse region and a pad region. A substrate(100) including a fuse region and a pad region is prepared. An interlayer dielectric(102) having an opening is formed on the fuse region and the pad region. A first conductive layer pattern(106) is used as a fuse by filling a conductive material into the opening. A second conductive layer pattern(108) is connected to a pad pattern. A protective layer(110) for protecting the first and second conductive layer patterns is formed on the interlayer dielectric. A first and second openings for exposing upper surfaces of the first and second conductive layer patterns are formed by etching a part of the protective layer. A capping layer pattern(114) is formed selectively on the upper surfaces of the first and second conductive layer patterns. A pad pattern(118) is formed on an upper surface of the protective layer adjacent to the second opening, a sidewall of the second opening, and a surface of the capping layer pattern positioned on the second conductive layer pattern.
Abstract:
An LCD(Liquid Crystal Display) is provided to minimize the change of an electric field according to a layer step on a substrate, thereby displaying the high quality image. First and second substrates(100,200) are located oppositely with each other. A liquid crystal is arrayed between the first and second substrates. A storage electrode(120) is formed on the first substrate. A pixel electrode(180) is formed on the storage electrode. A common electrode(240) is formed on the second substrate and has a domain division member for dividing the pixel electrode forming area into plural domains. A transparent insulating layer pattern is formed between the storage electrode and the pixel electrode and has an opening(175) for covering the overlapped portion of the storage electrode and partially exposing the storage electrode. The domain division member is a partially incised pattern of the common electrode or a protrusion formed on the common electrode.

A conductive line for a semiconductor device, a forming method thereof, a flash memory device having the same and a fabricating method thereof are provided to reduce a parasitic capacitance due to an etch barrier layer by forming the etch barrier layer to have a thin thickness. Plural bottom conductive structures which are defined by an insulation layer is positioned on a substrate(10). A first interlayer dielectric pattern(11a) is positioned on the insulation layer through which a contact plug(14a) penetrating the insulation layer comes in contact with the substrate. An etch barrier layer(12) is formed on the contact plug and the first interlayer dielectric. A second interlayer dielectric pattern(13a) is positioned on the etch barrier layer through which plural conductive lines(15a) electrically connected to the contact plug passes.
Abstract:
비휘발성 기억 소자의 형성 방법을 제공한다. 이 방법에 따르면, 기판에 활성영역을 한정하는 소자분리막을 형성한다. 이때, 소자분리막의 상부면을 기판의 표면 보다 높게 형성하여, 기판 표면 보다 높은 소자분리막의 상부(upper portion)로 둘러싸인 갭 영역을 형성한다. 활성영역 상에 터널 절연막을 형성하고, 기판 전면 상에 플로팅 게이트막을 형성한다. 기판에 수소 어닐링을 수행하여 플로팅 게이트막을 리플로우시켜 갭 영역을 채운다. 리플로우된 플로팅 게이트막을 소자분리막이 노출될때까지 평탄화시키어 플로팅 게이트 패턴을 형성한다.
