  • Solid-state imaging device
    Patent number: 6731337
    Abstract: A solid-state imaging device includes a photodiode including a well region of a first conductivity type, a first impurity region of a second conductivity type, and a heavily doped impurity region of a first conductivity type formed on the first impurity region. The solid-state imaging device further includes a gate electrode that transfers charges accumulated in the photodiode and a readout region composed of an impurity region of a second conductivity type. A second impurity region of a second conductivity type extends from the first impurity region of a second conductivity type to the readout region. Furthermore, an impurity region of a first conductivity type is formed below the gate electrode. This configuration facilitates complete charge transfer from the photodiode in a readout process. This solid-state imaging device barely generates random noise and can pick up moving images with high definition.

  • Mounting structure of a solid-state image pick-up device
    Patent number: 6665016
    Abstract: A mounting structure includes a fixing plate to which an image pick-up device is fixed; screw holes formed on a supporting member; a first female threaded portion and a second female threaded portion having a smaller diameter than the first female threaded portion, formed in each screw hole; cylindrical adjustment members which are screwed into the screw holes, respectively, and are rotatable to adjust the axial position thereof; and set screws which are rotatably inserted through the fixing plate and respective axial holes of the cylindrical adjustment members to be engaged with the second female threaded portions of the screw holes to hold the fixing plate between each head portion of the set screws and each cylindrical adjustment member, respectively.
