Title: 역전압 보호 회로를 구비한 파워 디바이스
IPC: H01L29/732
Filed: 1992-04-30
Granted: 2001-04-16
Abstract: 제어 회로 부품 및 최소한 하나의 파워 디바이스를 가진 파워 집적 회로에 있어서, 통상적으로 상기 회로 부품은 아래 기판과 반대인 도전형의 분리 "웰들"내에 배치되므로써 상기 파워 디바이스로부터 절연된다. 그러나, 이들 파워 집적 회로가 공급 전압이 우연찮게 역으로 될 수 있는 응용 분야(예컨대, 자동차 전자학)에 사용되는 경우에, 잠재적인 큰 손상 전류가 상기 회로 부품을 통해 흐를 수 있다. 이러한 큰 역전류가 흐르는 것을 방지하기 위해, 부가적인 p-n 접합이 상기 회로 "웰"내에 일체화되어, 원하지 않는 큰 역전류가 흐르는 것을 방지한다. 그러나, 이 부가적인 p-n 접합의 도입은 디바이스내에 수직 트랜지스터를 형성시키므로, 또다른 잠재적인 손상 전류 경로를 생성하고 또한 역브레이크다운 전압 문제를 야기시킨다. 이런 문제점들을 해결하기 위해, 두개의 직렬 접속 MOS 스위칭 트랜지스터를 채용하는 역전압 보호 회로가 수직 트랜지스터의 베이스로부터 전류를 우회시키기 위해 사용된다. 또한, 이 역전압 보호 회로의 효율은 회로의 브레이크다운 특성들을 한층 강화시키는 게이트 바이어스 전압을 발생시키는 역할을 하는 집적된 바이어스 회로를 부가하는 것에 의해 개선될 수 있다.
