Abstract
본 발명은, 생산성이 높고, 옴전극의 저저항화가 가능하고, 집적밀도가 높이며, 각 구성소정의 특성열화가 적고 또 수율이 높은 반도체장치를 제공하는 것을 그 목적으로 한다. 본 발명의 반도체장치의 옴전극은, GaAs 기판(1)상에 AuGe/Ni합금층(27), WSi층(18C) 및 Au층(17d)이 순차 적층된 구조를 지니고 있다. 상기 WSi층(18C)에 의해서 전극의 평탄성이 유지되고 또 Au층(17d)에 의해서 전극의 저저항화가 도모된다.An object of the present invention is to provide a semiconductor device having high productivity, low resistance of an ohmic electrode, high integration density, low characteristic degradation of each component, and high yield. The ohmic electrode of the semiconductor device of the present invention has a structure in which AuGe / Ni alloy layer 27, WSi layer 18C and Au layer 17d are sequentially stacked on GaAs substrate 1. The WSi layer 18C maintains the flatness of the electrode, and the Au layer 17d reduces the resistance of the electrode.
