Claims (6)
- 집적 회로의 하나의 접속 패드(4)와 각각 접속된 2개의 제 2도전형(n, n+, n-) 도핑 영역(2) 사이에 가로 방향으로 배치된 절연 영역(1)을 제 1도전형(p)의 기판(3)내에 포함하며,상기 도핑 영역(2) 및 절연 영역(1)은 하나의 기생 반도체 소자(Tpar)를 형성하고,상기 접속 패드(4) 중 적어도 하나의 접속 패드(4)는 필드 옥사이드 트랜지스터의 형태로 된 적어도 하나의 ESD-방지 구조물(TESD)을 통해 집적 회로의 하나의 공급 전위(VSS) 및/또는 다른 접속 패드(4)와 각각 접속되며, 이 경우 모든 ESD-방지 구조물(TESD)은 정전기적 방전의 경우에 방전 전류의 흐름을 유도하는, 필드 옥사이드 트랜지스터의 채널의 형태로 된 방전 경로를 포함하고,상기 절연 영역(1)의 가로 방향 길이(L)는 ESD-방지 구조물(TESD)의 최장 방전 경로 길이보다 길거나 또는 같은 것을 특징으로 하는 집적 회로.
- 제 1항에 있어서,상기 절연 영역(1)의 길이(L)는 적어도 ESD-방지 구조물(TESD)의 최장 방전 경로 길이의 1.5배인 것을 특징으로 하는 집적 회로.
- 제 1항 또는 제 2항에 있어서,접속 패드(4) 중 하나의 접속 패드는 집적 회로의 접속핀(5)과 접속되어 있는 것을 특징으로 하는 집적 회로.
- 제 1항 또는 제 2항에 있어서,접속 패드(4) 중 하나의 접속 패드가 전극, 예컨대 테스트 프로드(test prod)와 접속될 수 있는 것을 특징으로 하는 집적 회로.
- 제 1항 또는 제 2항에 있어서,상기 절연 영역(1)은 LOCOS-영역인 것을 특징으로 하는 집적 회로.
- 제 1항 또는 제 2항에 있어서,상기 절연 영역(1)은 트렌치 절연인 것을 특징으로 하는 집적 회로.
