Abstract
A surface acoustic wave device with electrodes having a metallization of a first layer of substantially pure titanium and a second layer of an alloy of aluminum and titanium. The titanium comprises about 0.1% to about 1.0% by weight of the alloy with aluminum substantially comprising the remainder of the alloy. The titanium of the first layer provides good adhesion and preferential Al(,) grain orientation for the second layer. The titanium of the second layer provides good mechanical strength for improved power handling while the aluminum maintains high electrode conductivity. Small grain structure in the metallization further improves mechanical strength.
