Support for acoustic resonator and corresponding integrated circuit

摘要

An integrated circuit includes at least one interconnection level and an acoustic resonator provided with an active element and a support. The includes at least one bilayer assembly having a layer of high acoustic impedance material and a layer of low acoustic impedance material. The support further includes a protruding element arranged on a metallization level of the interconnection level, making it possible to produce an electrical contact between an interconnection level and the active element of the acoustic resonator.
