Abstract
A new and improved semiconductor thermoelectric device which could be used either as a thermoelectric cooler or as a thermopile heat sensor with high output voltage. This invention comprises an array of thermocouples fabricated on a semiconductor substrate. The thermocouples comprise segments of tantalum and segments of conductively doped polysilicon as two electric conductor materials of different thermoelectric properties which are buried between two layers of oxide. A layer of metal as a heat collector covers the surface of the thermopile and distributes heat from a nearby heat source.
