Abstract:
A bulk acoustic resonator includes a substrate, a first electrode disposed above the substrate, a piezoelectric body disposed on the first electrode and including a plurality of piezoelectric layers each including aluminum nitride with a doping material, and a second electrode disposed on the piezoelectric body, where at least one of the piezoelectric layers is a compressive piezoelectric layer formed under compressive stress.

Claim (Index 1):
A bulk acoustic resonator comprising:\n a substrate; a first electrode disposed above the substrate; a piezoelectric body disposed on the first electrode and including aluminum nitride with a doping material; and a second electrode disposed on the piezoelectric body, wherein the piezoelectric body comprises a first portion and a second portion, and the first portion is closer to the first electrode than the second portion, and a ratio (c/a) of a lattice parameter of the first portion in a c-axis direction to a lattice constant of the first portion in an a-axis direction is higher than a ratio (c/a) of a lattice parameter of the second portion in a c-axis direction to a lattice constant of the second portion in an a-axis direction.
