What type of solution (vendor and type) are you using? The vendor might have
an additive to improve the surface roughness.

Subject: [mems-talk] Electroplating Gold


Dear All,

I am trying to electroplate gold on top of silica: for that I sputtered a
few nm Ti and then few nm of gold on top of the silica and place that in
the electroplating solution at 50C. I used a current of 50mA that will
give us around 2 micron thick layer of gold in 20min.

The surface appear with a lot of roughness.... Could somebody give me some
advice? Am I using the correct parameters for current and temperature to
get an uniform layer?

Thank you very much for your help!

Sonia.
