Abstract
Description
이때, 공통 소스/드레인 영역(240)의 정션 아래 부분은, 도 5a와 같이, 공핍층(250)이 형성되기 마련인데, 이 공핍층(250)은 실리콘 액티브 영역의 두께보다 두껍게 형성될 경우에는 도 5b와 같이 전도 통로를 막을 수도 있게 된다. 그러나 이러한 경우에도 바디가 플로팅되어 있는 통상적인 SOI MOSFET보다 우수한 항복 전압 특성을 보이는 것을 시뮬레이션을 통해 알 수 있었다. 도 6a는 공핍층이 전도 통로를 막지 않은 경우이고, 도 6b는 공핍층이 전도 통로를 막은 경우를 나타내는데, 이들 시뮬레이션 결과로부터 kink 효과나 항복 전압 특성이 상대적으로 안 좋은 PD 구조에서도 종래 통상적인 경우 보다 우수한 특성 향상을 보일 수 있다는 것을 알 수 있다.
