A Novel CMOS-SOI High-Responsivity Thermopile for Thermal Sensing Applications

Elisabetta Moisello et al.

Summary: This paper presents a novel micromachined high-responsivity thermopile sensor that is fully compatible with standard CMOS-SOI processes. The proposed sensor features a versatile mosaic structure with a series and/or parallel connection of 128 60μm x 60μm pixels. Two versions of the sensor are presented and characterized, with the most performing version surpassing other state-of-the-art thermopile sensors in responsivity. The application of the most performing sensor as a proximity and motion detector is also verified through measurements.
