hello,

I have some gold electrodes onto my COC (topas) substrate and I want to isolate them and just let the surface of the electrodes free (no the connections): We tried SU-8 as passivative layer but the substrate becomes very fragile. I wonder if the solvent of the SU-8 is not compatible with COC. Someone did ever seen this? What kind of insulator layer can I use?

Thanks in advance!
