    Abstract: The resonator has a piezoelectric layer (3) placed between two electrodes (1, 2). An electrical heating resistor (9) is placed in thermal contact with the electrode (1). The temporary heating of the electrode (1) permits to partially evaporate a material constituting the electrode (1) to make the electrode (1) thinner for adjusting resonance frequency. An independent claim is also included for a method of producing a thin film bulk acoustic resonator or a solidly mounted resonator.

    Abstract: The electronic component has two resonators (3, 4) that are disposed on an upper surface of a silicon substrate. Each resonator has a lower electrode in contact with the upper surface, a piezoelectric active component disposed on the lower electrode and an upper electrode disposed on the active component. The respective lower electrodes are made of aluminum and molybdenum, to obtain frequencies at different resonance. Independent claims are also included for the following (a) an integrated circuit including the electronic component (b) a hybrid circuit including the electronic component (c) a filter comprising a electronic component (d) a process of fabrication of the electronic component.
