Abstract:
A method of fabricating a thermoelectric device comprising:a grooved block fabrication process of forming grooved blocks composed of an n-type thermoelectric semiconductor and a p-type thermoelectric semiconductor, respectively, each provided with a plurality of grooves formed at a same pitch and parallel with each other in only one direction, leaving a depthwise portion of respective grooved blocks intact; a fitting process of fitting the grooved blocks composed of the n-type thermoelectric semiconductor and the p-type thermoelectric semiconductor formed, respectively, by said grooved block fabrication process to each other such that surfaces of the respective grooved blocks, with the grooves formed thereon, face each other; an adhesion process of forming an integrated block by adhering the grooved block composed of the n-type thermoelectric semiconductor and the grooved block composed of the p-type thermoelectric semiconductor, fitted to each other by said fitting process, to each other after filling up gaps in fitting parts between the respective grooved blocks with an adhesive insulation member; a second grooving process of forming a plurality of grooves in the integrated block formed by said adhesion process, in the direction crossing the direction of the grooves formed by said grooved block fabrication process, leaving a depthwise portion of the integrated block intact; a solidification process of filling up the grooves formed by said second grooving process with an adhesive insulation member and solidifying the same; and a thermoelectric semiconductor pieces exposure process of exposing n-type and p-type thermoelectric semiconductor pieces by removing all portions of the integrated block wherein the adhesive insulation member filling up the grooves is solidified in said solidification process, other than the fitting parts where the grooved block composed of the n-type thermoelectric semiconductor and the grooved block composed of the p-type thermoelectric semiconductor are fitted to each other.
