When in contact, titanium and gold form a galvanic corrosion couple. In the presence of an electrolyte, such as in wet chemical etching or if there is ionic material trapped in the films, interfacial corrosion can occur, giving a loss of adhesion. To disrupt this galvanic corrosion couple, a layer of platinum or palladium can be deposited between the titanium and the gold.f Thus, a metallization system might be ... [Pg.382]
