Patent ID: 8193597

Claim:
A device, comprising: a first substrate having a first aperture therethrough from a first side of the first substrate to a second side of the first substrate; a first semiconductor die having at least a first acoustic transducer, the first semiconductor die being provided on the first side of the first substrate such that the first acoustic transducer is aligned with the first aperture in the first substrate; a second substrate having a second aperture therethrough from a first side of the second substrate to a second side of the second substrate; a second semiconductor die having at least a second acoustic transducer, the second semiconductor die being provided on the first side of the second substrate such that the second acoustic transducer is aligned with the second aperture in the second substrate; and a dual in-line package having a recess therein; wherein the first and second substrates are mounted on the dual in-line package such that the second substrate is adjacent to, and in parallel with, the first substrate, wherein the first sides of the first and second substrates, and the recess of the dual in-line package, together define a cavity, and wherein the first and second semiconductor dies are disposed in the cavity.
