Patent ID: 8749010

Claim:
An infrared imaging device comprising: a substrate having a detection region, an interconnection region and support region provided between the detection region and the interconnection region, the substrate having a connection layer provided in the interconnection region; a detecting section provided on the detection region, the detection section including: an infrared absorbing section provided above and spaced from the substrate and configured to absorb infrared radiation; and a thermoelectric converting section provided between the infrared absorbing section and the substrate, spaced from the substrate, thermally connected to the infrared absorbing section, and configured to convert temperature change due to the infrared radiation absorbed in the infrared absorbing section to an electrical signal; an interconnection provided on the interconnection region and configured to read the electrical signal; a contact plug extending from the interconnection toward the connection layer, the contact plug being electrically connected to the interconnection and the connection layer, the contact plug having a first end on a side of the substrate; and a support beam provided above the interconnection region, the support beam including a support beam interconnection and supporting the detecting section above the substrate, a first end portion of the support beam interconnection being connected to the first end a second end portion of the support beam interconnection being directly connected to the thermoelectric converting section, the support beam interconnection extending at a height of the first end in a plane perpendicular to a direction from the substrate toward the detecting section, and the support beam interconnection being configured to transmit the electrical signal from the thermoelectric converting section via the contact plug to the interconnection.
