Abstract

A CMOS-MEMS integrated device and a method for forming such a device are disclosed. The integrated device includes a double released MEMS infrared sensor. The double released MEMS sensor is a free-standing sensor over a lower sensor cavity which is etched into the substrate of the device. The free-spending MEMS sensor is devoid of a support dielectric membrane which supports the MEMS sensor, resulting in the MEMS sensor being suspended over the lower sensor cavity. The support dielectric is removed by a second release process. The second release process may also remove a protective dielectric layer over the MEMS sensor. The MEMS sensor without the protective dielectric layer enhances sensor sensitivity. In other cases, the free-standing MEMS sensor may include an absorber thereover. The absorber enhances sensor sensitivity.
