Patent ID: 8889453

Claim:
A method for manufacturing a thermoelectric element in which P-type thermoelectric materials and N-type thermoelectric materials are alternately joined between a pair of substrates, the method comprising: (a) preparing a P-type thermoelectric mixture powder and a N-type thermoelectric mixture powder in which a thermoelectric material powder and a low-melting metal powder are mixed at a predetermined ratio, respectively; (b) locating a support having a plurality of holes with a predetermined pattern on a first substrate; (c) filling the corresponding holes of the support with the P-type thermoelectric mixture powder and the N-type thermoelectric mixture powder; (d) packing the P-type and N-type thermoelectric mixture powders filled in the holes; (e) separating the support from the first substrate; (f) locating a second substrate to the other side of the thermoelectric mixture powders to be opposite to the first substrate; and (g) thermally treating the thermoelectric mixture powders at a temperature lower than a melt point of the thermoelectric material to join the thermoelectric mixture powders to the first and second substrates.
