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.
