Abstract:
A semiconductor device including an MOB(moisture/oxygen barrier) having an electrically disconnected region is provided to reduce general influence of noise upon a semiconductor device by avoiding a transfer of noise. A semiconductor device includes a digital region(110), an analog region(120) and an MOB(130) formed outside the peripheral part of the digital region and the analog region. The MOB includes a conductive line, and the conductive line includes an electrically disconnected region in its intermediate portion. The MOB can electrically be connected to an impurity implantation region of the substrate. The periphery of the MOB can be made of a material with a lower dielectric constant than a silicon oxide layer.

Abstract:
PURPOSE: A gate forming method for preventing a short between a gate and a self-aligned contact and a semiconductor device including the gate are provided to prevent a top layer and a resistance structure from being removed by forming a second photoresist to cover the resistance structure and a peripheral region of the resistance structure. CONSTITUTION: A metal gate(121) of a transistor is formed near an insulation layer on a substrate(100). A metal gate includes a first metal(177) and a second metal. A hard mask including an opening is formed on the substrate with the metal gate. A metal pullback process is performed to etch a part of the upper side of the metal gate with a preset depth. A protection layer(212) is deposited on the hard mask and the etched metal gate. A CMP is performed to remove the hard mask and the protection layer.

커패시터 형성 방법을 제공한다. 이 방법은 반도체 기판 상에 하부 전극을 형성하고, 상기 하부 전극이 형성된 기판의 전면에 층간절연막을 형성한다. 상기 하부 전극이 노출되도록 상기 층간절연막을 평탄화한다. 상기 하부 전극 상에 커패시터 유전막을 개재하여 상부 전극을 형성한다. 본 발명에서 상기 상부 전극의 가장자리는 상기 하부 전극 주변의 층간절연막까지 오버행되도록 형성하는 것이 특징이다. 따라서, 커패시터의 상부 전극이 하부 전극과 중첩되지 않고 하부 전극 외곽으로 그 가장자리가 오버행된 구조를 가지기 때문에 상부 전극을 패터닝하는 과정에서 커패시터 유전막에 금속 잔유물이 부착되더라도 하부 전극과 상부 전극 사이의 누설 전류 경로가 형성되지는 않는다.
