Abstract:
A BAW device includes a substrate, a first reflector, and at least two BAW transducers. The first reflector resides over the substrate and has a plurality of reflector layers. A first BAW transducer resides over a first section of the first reflector, has a first series resonance frequency, and has a first piezoelectric layer of a first thickness between a first top electrode and a first bottom electrode. The second BAW transducer resides over a second section of the first reflector, has a second series resonance frequency that is different than the first series resonance frequency, and has a second piezoelectric layer of a second thickness, which is different than the first thickness, between a second top electrode and a second bottom electrode.

Claim (Index 26):
A Bulk Acoustic Wave (BAW) device comprising:\n a substrate comprising a planar surface; a first reflector over the substrate and comprising a first plurality of reflector layers; a first BAW transducer over a first section of the first reflector that is over the planar surface of the substrate and comprising a first piezoelectric layer of a first thickness between a first top electrode and a first bottom electrode; and a second BAW transducer over a second section of the first reflector that is over the planar surface of the substrate and comprising a second piezoelectric layer of a second thickness between a second top electrode and a second bottom electrode, wherein:\n the first thickness is different than the second thickness; \n in the first section of the first reflector beneath the first BAW transducer, a first average thickness of each of the first plurality of reflector layers is approximately one-quarter the wavelength (\u03bb/4) of a first acoustic wave for a frequency at which a first acoustic mode of a first type operates in the first BAW transducer and a second acoustic wave for a second frequency at which a second acoustic mode of a second type operates; \n in the second section of the first reflector beneath the second BAW transducer, a second average thickness of each of the first plurality of reflector layers is approximately one-quarter the wavelength (\u03bb/4) of a third acoustic wave for a frequency at which the first acoustic mode of the first type operates in the second BAW transducer and a fourth acoustic wave for a fourth frequency at which the second acoustic mode of the second type operates; and \n the first average thickness is different than the second average thickness.
