Abstract:
A method for fabricating a thermoelectric converter having a plurality of series-connected thermoelement cells, each of which has a first body made of thermoelectric material of a first conduction type that is connected by a first electrical conductor track to a second body made of thermoelectric material of a second conduction type, where the thermoelement cells are connected to one another in series by a second electrical conductor track and are arranged in a sandwich-like manner between a first substrate wafer and a second substrate wafer, the method comprising:forming a first electrically conductive layer on a main area of the first substrate wafer; applying a first layer made of thermoelectric material, which is of the first conduction type, to the first electrically conductive layer; patterning the first layer made of thermoelectric material to form the first bodies; patterning the first electrically conductive layer to form the first conductor tracks; forming a second electrically conductive layer on a main area of the second substrate wafer; applying a second layer made of thermoelectric material which is of the second conduction type to the second electrically conductive layer; patterning the second layer made of thermoelectric material to form the second bodies; patterning the second electrically conductive layer to form the second conductor tracks; and connecting the first substrate wafer and the second substrate wafer such that the first and second electrical conductor tracks and the first and second bodies are arranged between the first and second substrate wafers to form the plurality of series-connected thermoelement cells.
