Thin film thermopiles are widely used as small size sensors, in particular to sense infra-red thermal radiations. In this paper a method for designing and fabrication of thin films Bi-Cu thermopiles in linear array of 8 and 11 elements in series and mono-layer is introduced. Also, fabrication of Bi-Sb and Bi-Cu thin film thermopiles, which are used as IR radiation sensors, made in multilayer form with 100 series junctions in circular shape are presented. The samples are fabricated on a PCB board with double-sided copper laminated as a substrate. The results of our measurements show that the output voltage produced due to temperature difference between junctions, is very sensitive and linear to temperature difference.
