Patent ID: 8525278

Claim:
A device, comprising: a first substrate having a MEMS device disposed on a frontside of the first substrate; a second substrate including an integrated circuit (IC) and having a frontside and an opposing backside, wherein the IC includes a multi-layer interconnect (MLI) structure, wherein the MLI structure includes: a first conductive line, a second conductive line overlying the first conductive line, a conductive via connecting the first and second conductive line, a dielectric material interposing the first and second conductive lines; and wherein the second substrate further includes a through-silicon via (TSV) extending from the backside of the second substrate to the first conductive line; wherein a first bonding feature on the frontside of the first substrate is bonded to a second bonding feature on a backside of the second substrate; and wherein the TSV connects the second bonding feature and the first conductive line.
