Abstract:
A heat absorbing element  20  of a thin-film Peltier type is thermally connected with a surface of a semiconductor element body portion  10  through a heat conducting layer  15  which is an electrical insulator. The heat absorbing element  20  is comprised of a substance having a bulk thermal conductivity of 50 W/mK or more and a Seebeck coefficient of 300 μV/K or more.

Claim (Index 10):
A method for manufacturing a heat absorbing element of a thin-film Peltier type thermally connected with a surface of a semiconductor element through an electrical insulator,\n the method comprising: forming a lower metal film, a first conductivity type semiconductor layer, and a first metal sacrificial film in order on the semiconductor element through the electrical insulator; forming a first metal mask film for patterning the first conductivity type semiconductor layer from the first metal sacrificial film, and using the first metal mask film formed, patterning the first conductivity type semiconductor layer so as to form a plurality of first conductivity type semiconductor blocks from the first conductivity type semiconductor layer; forming a second conductivity type semiconductor layer and a second metal sacrificial film in order on the lower metal film including the first conductivity type semiconductor block; forming a second metal mask film for patterning the second conductivity type semiconductor layer from the second metal sacrificial film, and using the second metal mask film formed, patterning the second conductivity type semiconductor layer so as to form a plurality of second conductivity type semiconductor blocks from the second conductivity type semiconductor layer; selectively etching, by a lithography method, an electrode formation region of the semiconductor element in the lower metal film so as to expose the semiconductor element; selectively etching, by a lithography method, a portion between the first conductivity type semiconductor block and the second conductivity type semiconductor block in the lower metal film so as to form a plurality of lower electrodes from the lower metal film; selectively forming an insulation film on a portion between the semiconductor blocks and on a portion between the lower electrodes, followed by forming an upper metal film on the semiconductor blocks and on an exposed portion of the semiconductor element; and selectively etching, by a lithography method, the upper metal film so as to form an upper electrode and an electrode of the semiconductor element from the upper metal film.
