Sputter gold on Al piece

[Yongliang Yang]

Thank you for lab members' reply and sharing the valuable experience.

If only considering the adhesion, the gold can be directly deposited on Al without adhesion layer. But there is intermetallic (Purple plague) at Al-Au contact, which has different properties. So it is better to have adhesion layer. 

Best,

Hi, all,

I would like to sputter gold layer on an Al piece. I am not sure if I still need adherent layer such (Ti, Cr). Does anyone have experience on it.

BTW, the sputteiring will be done in our lab not in SNF due to contamination.

Best,
