  • Publication number: 20110186913
    Abstract: In a solid state imaging device with an electron multiplying function, in a section normal to an electron transfer direction of a multiplication register EM, an insulating layer 2 is thicker at both side portions than in a central region. A pair of overflow drains 1N is formed at a boundary between a central region and both side portions of an N-type semiconductor region 1C. Each overflow drain 1N extends along the electron transfer direction of the multiplication register EM. Overflow gate electrodes G extend from the thin portion to the thick portion of the insulating layer 2. The overflow gate electrodes G are disposed between both ends of each transfer electrode 8 in a longitudinal direction and the insulating layer 2, and they also function as shield electrodes for each electrode 8 (8A and 8B).

  • Publication number: 20110031377
    Abstract: A multi-port solid-state imaging device of one embodiment includes an imaging region and a plurality of units. The imaging region contains a plurality of pixel columns. The units are arrayed in a direction in which the pixel columns are arrayed, and generate signals based on charges from the imaging region. Each unit has an output register, a multiplication register, and an amplifier. The output register transfers a charge from one or more corresponding pixel columns. The multiplication register receives the charge from the output register to generate a multiplied charge. The amplifier generates a signal based on the multiplied charge from the multiplication register. The solid-state imaging device contains a region where the units are provided, and a first dummy region and a second dummy region located on both sides in the above-mentioned direction of the region. In each of the first dummy region and the second dummy region, a multiplication register and an amplifier are provided.

  • Publication number: 20110024606
    Abstract: A solid-state imaging device of an embodiment includes an imaging region, an output register, a corner register, a multiplication register, a first amplifier, a second amplifier, and a valve gate electrode. The output register is a transfer register that receives a charge transferred from the imaging region to transfer the charge. The output register is capable of selectively transferring a charge in one direction and in the other direction opposite to the one direction. The corner register transfers a charge transferred in one direction from the output register. The multiplication register receives a charge from the corner register and generates and transfers a multiplied charge. The first amplifier generates a signal based on a multiplied charge from the multiplication register. The second amplifier generates a signal based on a charge transferred in the other direction by the output register.

  • Publication number: 20100220839
    Abstract: An intraoral sensor 1 includes: a case 4 having a first plate-shaped portion 12 and a second plate-shaped portion 16 that face each other; a photodetecting element 34 contained in the case 4 so that a light incident surface faces the first plate-shaped portion 12; a cover 6a, arranged on the outer surface of the second plate-shaped portion 16, for covering an opening 16a; and fixing members 32a and 32b, arranged between the second plate-shaped portion 16 and the cover 6a, for fixing to the case 4 a signal cable 24 connected to the photodetecting element 34 extending via the opening 16a from the inside to the outside of the case 4. This enables improvement of a connection strength between the case of the imaging device and the signal cable extending from an opposite side of the imaging surface.
