Abstract
For a component operating with acoustic waves, it is proposed to arrange the electrode structure over a mechanically stable adaptation layer that serves to dissipate the electromechanical stresses. Further improvements of the output compatibility are achieved with additional intermediate layers and passivation layers applied on the sides or the entire surface over the electrode structure.
