Sreemanth, like everyone has been saying get clean good vacuum.  A dc
magnetron is all that is needed.  Gary

Subject: [mems-talk] Aluminum sputtering and evaporation


Hello All,

This is sort of a generalization of one of the previous questions - I am
trying to coat Aluminum films of thickness  around 150nm on quartz
substrates.. I have tried using RF-sputtering and also e-beam evaporation.
In both cases the film quality was not very good. There were these hillocks
forming all over the film. Could anyone please recommend any recipe for
obtaining hillock free Aluminum films.

Thanks,
Sreemanth
