Thin (~20nm) Cr or Ti film will be helpful. Also, plasma clean the substrate
before your deposition.

Good luck,

Subject: [mems-talk] Ni /Au adhesion

HI.

I have tried depositing Ni/Au(E-GUN) on bonding pad, but got poor adhesion.
(Ni=500A, Au=5000A)
So far, I tried Ni-Silide to improve the adhesion, but still can't work.
Is there any idea can improve Ni/Au adhesion?
