[labnetwork] Bismuth Deposition

[J Romans]

Hello Esteemed Colleagues -

We have a research group that is interested in depositing Bismuth. We are
leaning towards allowing this in an ebeam evaporator, but sputtering is
also a possibility.

Is anyone aware of any pitfalls or tips associated with either method of
deposition? Bi has health and flammability ratings of 1 ( compare Cr with
health 2 and flammability 1, which we do a lot of).

We are more concerned with the physical characteristics that might cause
splattering, contamination, incompatibilities with other processes,
difficulty cleaning shielding, etc.

Any information would be greatly appreciated.

Thanks,
