Abstract
A multi-layer thermoelectric module and a fabricating method thereof are provided. The module includes two thermoelectric element sets and a metal electrode set, in which the thermoelectric element sets are corresponding to different operating temperature ranges. Each thermoelectric element set includes a thermoelectric unit, an interfacial adhesion layer, a diffusion barrier layer and a high melting-point metal layer. In the method, the thermoelectric unit, the interfacial adhesion layer, and the diffusion barrier layer are sequentially formed on the thermoelectric unit. Then, two high melting-point metal layers are formed respectively on the electrode layers of the metal electrode set. Thereafter, a solid-liquid interdiffusion jointing step is conducted to use a low melting-point metal layer to react with the high melting-point metal layer for producing an intermetallic compound layer jointing the thermoelectric element set with the metal electrode set, and the low melting-point metal layer is consumed completely.
