METHODS OF FABRICATING THERMOELECTRIC ELEMENTS

摘要

Methods of fabricating a thermoelectric element with reduced yield loss include forming a solid body of thermoelectric material having first dimension of 150 mm or more and thickness dimension of 5 mm or less, and dicing the body into a plurality of thermoelectric legs, without cutting along the thickness dimension of the body. Further methods include providing a metal material over a surface of a thermoelectric material, and hot pressing the metal material and the thermoelectric material to form a solid body having a contact metal layer and a thermoelectric material layer.
