摘要
The AuGe/Ni/Au metallization is one of the most widely used contact structures in compound semiconductor devices. Many laboratories use a metal structure consisting of a AuGe eutectic (88 : 12) layer with, typically, 5% Ni. The influence of Ni proportion on the electrical parameters of contacts, the surface morphology and the volatile component loss during annealing were investigated. The results show that the effect of Ni proportion on the minimum value of specific contact resistance and on the surface morphology is much more significant than its effect on the optimum heat treatment temperature. © 1990.
