Electrode structure with improved power handling capability and method for producing

摘要

With acoustic waves operating component with a piezoelectric substrate (s), on which an aluminum comprehensive electrode structure (it) is applied, characterized in that below the electrode structure (it) to increase the power handling capability of the electrode structure, a mechanically stable adaptation layer (as) is arranged, wherein the adaptation layer (as) is made of copper, and that between an adaptation layer and the piezoelectric substrate (s), an intermediate adhesive layer (hs) is arranged, wherein the adhesion promoter layer (hs) al₂O₃ comprises.
