Abstract:
Acoustic resonator devices and filters are disclosed. An acoustic resonator includes a substrate and a piezoelectric plate having parallel front and back surfaces, the back surface attached to the substrate. An interdigital transducer (IDT) is formed on the front surface of the piezoelectric plate such that interleaved fingers of the IDT are disposed on a portion of the piezoelectric plate suspended over a cavity formed in the substrate.

Claim (Index 55):
A filter device, comprising:\n a substrate; a piezoelectric plate having parallel front and back surfaces, the back surface attached to the substrate; a conductor pattern formed on the front surface, the conductor pattern including a plurality of interdigital transducers (IDTs) of a respective plurality of resonators including a shunt resonator and a series resonator; a first dielectric layer having a first thickness deposited over the IDT of the shunt resonator; and a second dielectric layer having a second thickness less than the first thickness deposited over the IDT of the series resonator, wherein interleaved fingers of each of the plurality of IDTs are disposed on respective portions of the piezoelectric plate suspended over one or more cavities formed in the substrate, the first and second dielectric layers are at least one of SiO2 and Si3N4, and a difference between the first thickness and the second thickness is greater than or equal to 30 nm.
