Abstract

본 발명은 GaAs MESFET 또는 쇼트키 베리어 다이오드 등의 반도체 장치에 관한 것이다. 본 발명에 따른 GaAs MESFET는 균일성과 신뢰도를 향상시킨 항복전압을 갖고 있다. 또, 본 발명에 따른 쇼트키 베리어 다이오는 균일성과 신뢰도가 향상된 순방향과 역방향 전류-전압 특성을 갖는다.
본 발명의 반도체 장치의 제조방법에서는 먼저, 화합물 반도체 기판 위에 n+활성층이 형성되고, 그 위에 소스 전극과 드레인 전극이 형성된다. 그런다음, n+활성층내의 소스전극과 드레인 전극 사이에 플라즈마 공정에 의해 고-저항층이 형성된다. 고-저항층은 0.6∼0.8eV의 표면상태를 갖는다. 활성층과 쇼트키 접합을 형성하는 쇼트키 전극은 고-저항층 위에 형성된다.
