Abstract
반도체 소자의 소자분리막 및 그 제조방법에 대해 기재되어 있다. 이는 비활성 영역의 반도체 기판에 형성된 트렌치, 이 트렌치 내벽에 형성된 내벽산화막, 이 트렌치를 채우고 산화물로 형성된 제1 소자분리막 및 제1 소자분리막상에 형성되고 질화물로 형성된 제2 소자분리막을 포함하는 것을 특징으로 한다. 따라서, 본 발명에 의하면, 활성영역 주변의 소자분리막의 손상을 방지함으로써 소자들 간의 절연을 신뢰도 높게 달성할 수 있고 트랜지스터의 정션 누설을 방지할 수 있다.A device isolation film of a semiconductor device and a method of manufacturing the same are described. It includes a trench formed in a semiconductor substrate in an inactive region, an inner wall oxide film formed in the inner wall of the trench, a first device isolation film filled with the trench and formed of oxide, and a second device isolation film formed on the first device isolation film and formed of nitride. It is done. Therefore, according to the present invention, by preventing the damage of the device isolation film around the active region, the insulation between the devices can be achieved with high reliability and the junction leakage of the transistor can be prevented.
