Embodiment Construction

[0063] figure 1Shown is a ring-shaped semiconductor element 1 having a thermoelectric material 2 and a first frame portion 3 arranged on an inner peripheral surface 5 of the thermoelectric material 2 . The second frame portion 4 is arranged on the outer peripheral surface 6 of the thermoelectric material 2 . Even though the term "first frame portion" refers herein to the inner frame portion and the term "second frame portion" refers herein to the outer frame portion, such designations are not mandatory for various other embodiments of the present invention.

[0064] The outer peripheral surface 6 is the element surface 29 of the thermoelectric material 2 , which is opposed to the element surface 29 of the thermoelectric material 2 connected to the first frame portion 3 . The first frame part 3 has two opposite surfaces 7 , wherein an attachment surface 9 is formed on the surface 7 opposite to the thermoelectric material 2 . The thickness 8 of the first frame part 3 is formed...

Abstract

A semiconductor element (1) at least comprising a thermoelectric material (2) and a first frame part (3) which are non-positively connected to one another, the frame part (3) forming a diffusion barrier for the thermoelectric material (2) and an electrical conductor. The invention further relates to a method for producing the semiconductor element (1) of the invention as well as to a thermoelectric module (17) comprising at least two semiconductor elements (1) of the invention.

Description

technical field [0001] The invention relates to a semiconductor component and a method for its production, and to a thermoelectric module having a semiconductor component of this type or a semiconductor component produced by this method. Background technique [0002] Exhaust gases from a motor vehicle's internal combustion engine contain heat energy, which can be converted into electrical energy by a thermoelectric generator, for example, to charge a battery or some other energy storage device and / or to feed the required energy directly to an electrical load. In this way, the motor vehicle can be operated with improved energy efficiency and more energy can be obtained to operate the motor vehicle. [0003] A thermoelectric generator of this type has at least one thermoelectric module. A thermoelectric module comprises, for example, at least two semiconductor devices (p-doped and n-doped), provided on the upper and lower side of the module (facing the hot or cold side), with...
