Abstract

An electroacoustic component includes a substrate configured to carry acoustic waves. The electroacoustic component can be a guided bulk acoustic wave (GBAW) device, for example. A structured electric conductive layer is arranged on the substrate and an electrically dielectric layer (for example, aluminum oxide) is also arranged over the substrate.
