Adhesion of Pt on Si, SiO2 and Si3N4

The adhesion of Pt on the materials you mention is normally quite poor. An
adhesion-layer is normally used (e.g. CT, Ti, Pt).
We have sputtered Pt directly onto low-stress nitride in the past and the
adhesion there was fine (tested with scotch-test). Some people also make
Pt-silicide by depositing Pt directly on Si and then doing an anneal-step,
but I don't know if they take additional precautions to get proper adhesion
of the Pt on the Si.
Succes.

Jason

Hello Memsnetigens

     Can anybody tell me adhesion behaviour of sputtered and e-beam
evaporated Platinum layer on Si, Si3N4 and SiO2.
