Abstract

반도체와 금속 게이트가 서로 접하는 MESFET에 있어서, 반도체와 금속게이트 사이에 질화일(PN)층을 형성시켜 역방향 누설전류를 감소시키기 때문에 종래의 반도체와 금속게이트가 바로 접해있을때의 단점인 쇼트키 장벽을 높일수 있기 때문에 이상적인 쇼트키 다이오드 특성을 갖는 반도체 소자를 제공한다.In the MESFET in which the semiconductor and the metal gate are in contact with each other, a nitride nitride (PN) layer is formed between the semiconductor and the metal gate to reduce the reverse leakage current. Since it can increase, the semiconductor device which has the ideal Schottky diode characteristic is provided.
