hi: We at present are do a titanium coating on Silicon Nitride on which we deposit Gold (as gold does not stick to Nitride). I am looking for literature to find if we can replace titanium with any other material on which we can deposit Gold and at the same time this material is not sensitive to KOH etching (Titanium is sensitive to KOH etching). I tried to find some literature on this but no success. Can any one help me in my dilemma thanks Nick Graduate Student Auburn University --------------------------------- Do you Yahoo!? Yahoo!
