    Abstract: A thermal-type infrared solid-state imaging element is provided with a pixel having a diaphragm (1), a substrate, and a pair of supporting sections which support the diaphragm (1) by being spaced apart from the substrate. The supporting section has a first supporting section (2) on the same level as the diaphragm (1), and a second supporting section (3) on a level between the diaphragm (1) and the substrate. The second supporting section (3) is composed of a beam (4) having one or more bending points (8), a first contact section (5) on one end portion of the beam (4), and a second contact section (6) on the other end portion of the beam (4). The beam (4) and the second contact section (6) of the second supporting section (3) of each pixel exist underneath the diaphragm (1) of another pixel.

  • Patent number: 7947528
    Abstract: A back-illuminated type solid-state image pickup device (1041) includes read circuits (Tr1, Tr2) formed on one surface of a semiconductor substrate (1042) to read a signal from a photo-electric conversion element (PD) formed on the semiconductor substrate (1042), in which electric charges (e) generated in a photo-electric conversion region (1052c1) formed under at least one portion of the read circuits (Tr1, Tr2) are collected to an electric charge accumulation region (1052a) formed on one surface side of the semiconductor substrate (1042) of the photo-electric conversion element (PD) by electric field formed within the photo-electric conversion element (PD). Thus, the solid-state image pickup device and the camera are able to make the size of pixel become very small without lowering a saturation electric charge amount (Qs) and sensitivity.
