Hi, I want to deoposit a layer of gold on silicon wafers, but I'm not sure if I need to deposit an adhesion layer such as a layer of chrome underneath. If so, could you let me know if approximately 250 angstroms of chrome would be sufficent? Also, what thickness of gold would you suggest be depositied for onto a micro-electrode array.
