Abstract:
An acoustic resonator that prevents a radio frequency (RF) signal from being coupled to a cap substrate. An electronic device includes a first substrate (device substrate) of piezoelectric material having a top surface on which an electronic circuit including a film bulk acoustic resonator is formed, a second substrate (cap substrate) of low-resistivity material, a bottom surface of which is disposed opposing the top surface of the first substrate, and a side wall disposed between the top surface of the first substrate and the bottom surface of the second substrate. The side wall defines a cavity together with the top surface of the first substrate and the bottom surface of the second substrate, the cavity internally including the electronic circuit. A thin film of high-resistivity material is formed on at least a portion of the bottom surface of the second substrate to prevent an RF signal emitted from the electronic circuit from being coupled to the second substrate.

Claim (Index 25):
A method of manufacturing an electronic device, the method comprising:\n forming an electronic circuit including a bulk acoustic wave (BAW) resonator on a top surface of a first substrate formed of piezoelectric material; forming a thin film on at least a portion of a bottom surface of a second substrate formed of low-resistivity material; and forming a side wall between the top surface of the first substrate and the bottom surface of the second substrate, the side wall supporting the top surface of the first substrate and the bottom surface of the second substrate and defining a cavity internally including the electronic circuit together with the top surface of the first substrate and the bottom surface of the second substrate, the thin film being formed of high-resistivity material to prevent a radio frequency (RF) signal emitted by the electronic circuit from being coupled to the second substrate.
