> 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.
