Alkaline will dissolve positive photoresists. I think you might try negative photoresists instead since negative photoresists doesn't dissovle in alkakine. > Hi all, > > I was doing gold electroplating using cynide bath.I > was doing plating on Si wafer sputtered with gold > later covered with photoresist ,exposed and developed > and hardbaked. > > after doing the above i have tried AU electroplating.I > was going for very low current densities and very low > temperature and with optimum PH after very less time i > could obsevere the plating of gold but the Photoresist > is disturbed and the pattern was disturbed. > > Can i find any ways to improve adhesion of photoresist > on AU surface. > > Ur suggestions are highly appreciated. > > Thanks > Kris > > > __________________________________ > Do you Yahoo!? > The New Yahoo!
