Patent ID: 7638769

Claim:
A solid-state image sensing device comprising: a semiconductor substrate having a recess formed in the surface portion thereof; a readout wiring portion provided on the semiconductor substrate; a support structure portion disposed above the recess, and having a connecting wiring electrically connected to the readout wiring portion; and a cell unit disposed above the recess, and supported by the support structure portion, the cell unit comprising: an antenna disposed on the surface side receiving incident electric waves in the cell unit, and configured to generate electrical signals by receiving incident electric waves and to reflect infrared lights; an electrical resistor electrically connected to the antenna, and configured to vary the temperature of the cell unit by generating Joule heat corresponding to the electrical signals and to reflect the infrared lights; a thermoelectric conversion element electrically connected to the support structure portion, electrically insulated from the antenna and the electrical resistor, and thermally connected to the electrical resistor, to generate electrical signals by detecting the temperature variation of the cell unit; and a member to reflect infrared lights provided on a surface side receiving the incident electric waves in the cell unit, and configured to be provided on a surface portion not covered by the antenna in the cell unit other than the electrical resistor.
