Hi, I would like to use electron beam evaporation in order to evaporate silica on a gold substrate for isolation purposes. I have tried this but I did not get adhesion between SiO2 and gold. Does anyone have any suggestions to what adhesion layer and how much of it I should use in order to acheive an SiO2 layer of 100 nm on sputtered gold. I do not have a CVD system so i need to use thermal evaporation. Regards, Leyla Soleymani University of Toronto l.soleymani@utoronto.ca
