Abstract

본 발명은 ESD 보호회로의 구조 및 제조방법에 관한 것으로, ESD(Electrostatic-Discharge) 특성을 개선하여 과잉전압으로 인한 내부회로의 파괴를 방지하도록 한 것이다.
본 발명에 따른 ESD 보호회로의 구조는 패드를 통해 내부회로쪽으로 인가되는 과잉 전압을 차단시켜 주는 반도체 소자의 ESD 보호회로에 있어서, 상기 ESD 보호회로로부터 약 1000 ㎛ 반경이내에 형성되는 ESD 보호회로 및 내부회로의 각 능동소자의 게이트 절연막 두께가 약 1000 ㎛ 반경이외에 형성되는 능동소자의 게이트 절연막 보다 두껍게 형성되어 있는 것을 특징으로 한다.
또한 본 발명에 따른 ESD 보호회로의 제조방법은 패드를 통해 내부회로쪽으로 인가되는 과잉전압을 차단시켜 주는 반도체소자의 ESD 보호회로에 있어서, 반도체기판상에 필드영역과 활성영역을 격리형성하여 ESD 보호회로부와 내부회로부를 정의하는 단계; 상기 ESD 보호회로로부터 1000 ㎛ 반경이내의 반도체기판상의 활성영역에 이 영역내에 형성되는 능동소자의 게이트 절연막을 상기 약 1000 ㎛ 반경이외에 형성되는 능동소자의 게이트 절연막 보다 두껍게 형성하는 단계를 포함하여 이루어진다.
