Yousef, What is the compelling need to use a refractory metal in this application? Is it exposed to a higher than usual temperature regime after the damascenation step?(or that 'after damascening'?)
Why not platinum? it cannot be cost as the small size trace area will not cost much and Pt is far less brittle than W?
Or are there other considerations?
