  • Patent number: 8664510
    Abstract: The infrared ray absorbing film 2 is provided with a first layer 21 containing TiN and a second layer 22 containing an Si based compound, converting energy of infrared ray made incident from the second layer 22 to heat. TiN is high in absorption rate of infrared ray over a wavelength range shorter than 8 ?m, while high in reflection rate of infrared ray over a wavelength range longer than 8 ?m. Therefore, if an Si based compound layer excellent in absorption rate of infrared ray over a longer wavelength range is laminated on a TiN layer, infrared ray over a wavelength range lower in absorption rate on the TiN layer can be favorably absorbed on the Si based compound layer, and also infrared ray in an attempt to transmit the Si based compound layer can be reflected on a boundary surface of the TiN layer and returned to the Si based compound layer.

  • Publication number: 20140026934
    Abstract: A three-dimensional thermoelectric energy harvester and a fabrication method thereof. Low-resistivity silicon is etched to form a plurality of grooves and silicon columns between the grooves, and an insulating layer is formed on a surface of the groove, and thermoelectric columns are fabricated by using a thin-film deposition technique, so that the thermoelectric column and a neighboring silicon column form a thermocouple pair; and then, a metal wiring is fabricated by processes such as etching and deposition, followed by thinning of the substrate and bonding of the supporting substrates, thereby completing fabrication of the three-dimensional thermoelectric energy harvester. Fabrication of the thermocouple pair structure by one thin-film deposition process simplifies the fabrication process. The thermocouple pair using silicon ensures a high Seebeck coefficient. The use of vertical thermocouple pairs having a column structure improves the mechanical stability of the thermoelectric energy harvester.
