Abstract

Thermoelectric cooler for providing sub-ambient cooling to an object and method of fabricating same. In one form, the thermally conducting but electrically insulating substrate interfaces used in conventional thermoelectric coolers are replaced by ultra-thin semiconductor substrates having a plurality of doped regions. Diodes formed in the semiconductor substrates are maintained in a reverse biased state to provide the desired electrical isolation necessary for operating the thermoelectric coolers. The reverse biased state is maintained by either the inherent properties resulting from forming the diode in the semiconductor material or through application of a bias voltage to the semiconductor substrates though a layer of conductive material deposited on the outermost surfaces of the substrates.
