Title: 반도체용 압력센서
IPC: H01L29/84
Filed: 1997-11-03
Abstract: 압력센서는 압전저항식의 효과에 근거를 두고 제안하고 있다. 여기서 멤브레인위에 배치되어 있는 저항이 외부로 부터 발생되는 압력에 의해서 변형이 일어나고, 또한 이 멤브레인의 변형 때문에 자신의 저항이 변하게 된다. 이러한 저항이 균등하게 그리고 민감하게 내부의 기계적인 방해응력에 의한 변형에 반응하기 때문에, 따라서 상쇄저항을 이용하여 내부의 기계적인 방해응력을 제거하고자 하는 구조가 고안되었다. 이러한 구조는 그밖에 집적된 센서에 대해서 히스테리시스를 상쇄하는데에 사용하고 있으며, 또한 이러한 히스테리시스는 주로 금속화된 표면의 압력센서와 이의 온도에 따른 항복을 일으키게 한다.
