Dear members, I have been working on gold interconnects for low temperature applications. However, at >600deg.C, the gold wire begins to diffuse into the top platinum layer. The major effect of this is to reduce time of failure in terms of device performance. Does anyone have a suggestion as to what binary metallization(top metal + wire interconnect) scheme could be implemented without any evident interfacial disturbance at 600deg.C. Your response to this and any relating information will be appreciated. Thank you. Robert S.
