Patent ID: 8827550

Claim:
An integrated circuit comprising: an interconnect layer including a layer of a dielectric material and a plurality of interconnects extending through the layer of the dielectric material, wherein the layer of the dielectric material comprises a channel formed therein, wherein sidewalls of the channel are formed by the dielectric material; a micro-electro-mechanical system (MEMS) resonator structure to provide an output signal corresponding to a temperature detected by the resonator structure, wherein a metal portion of the resonator structure is disposed within the channel, wherein the metal portion of the resonator structure includes exterior sides which each face a respective opposing sidewall formed by the dielectric material, wherein an air gap separates the exterior sides of the metal portion of the resonator structure each from the respective opposing sidewall formed by the dielectric material, the air gap to allow the metal portion of the resonator structure to resonate within the channel; and a seal enclosing the MEMS resonator structure with the interconnect layer, wherein one or more vias extend through the seal and couple to the resonator structure, wherein the resonator structure is suspended in the channel with the one or more vias.
