Abstract: 화합물 반도체 장치에서는, 패드 전극 하에 게이트 금속층을 형성하고 있었지만, 매립 게이트 전극 구조의 경우에는, 패드 전극 하층의 게이트 금속층이 경질화하여, 와이어 본딩 시의 불량이 다발하였다.  HEMT에서 게이트 금속층을 형성하지 않고, 패드 금속층만으로 패드 전극을 형성한다.  패드 전극의 하방은 고농도 불순물 영역을 형성하고, 패드 전극을 기판에 직접 고착한다.  고농도 불순물 영역에 의해 소정의 아이솔레이션을 확보할 수 있기 때문에, 종래 마찬가지의 질화막 불필요한 구조로, 게이트 금속층이 경질화함에 따른 와이어 본딩 시의 불량을 더 회피할수 있다.  따라서 HEMT의 특성을 향상시키는 매립 게이트 전극 구조에서도 신뢰성 향상, 수율 향상을 실현할 수 있다.
