  • Patent number: 8592874
    Abstract: In each of pixels 10 arranged in an array pattern, an insulating isolation part 22 electrically isolates adjacent photoelectric conversion elements 11, and the photoelectric conversion element 11 and an amplifier transistor 14. The insulating isolation part 22 constitutes a first region A between the photoelectric conversion elements 11 where the amplifier transistor 14 is not arranged, and a second region B between the photoelectric conversion elements 11 where the amplifier transistor 14 is arranged. A low concentration first isolation diffusion layer 23 is formed below the insulating isolation part 22 constituting the first region A, and a high concentration second isolation diffusion layer 24 and a low concentration first isolation diffusion layer 23 are formed below the insulating isolation part 22 constituting the second region B. A source/drain region of the amplifier transistor 14 in the second region B is formed in a well region 25 formed simultaneously with the second isolation diffusion layer 24.

  • Patent number: 8471351
    Abstract: Each of pixels 10 arranged in an array pattern includes a photoelectric conversion element 11, a transfer transistor 13 for transferring charges to a floating diffusion layer 12, and an amplifier transistor 14 for outputting the transferred charges to an output line. An insulating isolation part 22 isolates the adjacent photoelectric conversion elements 11, and isolates the photoelectric conversion element 11 and the amplifier transistor 14. The insulating isolation part 22 constitutes a first region A between the photoelectric conversion elements 11 where the amplifier transistor 14 is not arranged, and a second region B between the photoelectric conversion elements 11 where the amplifier transistor 14 is arranged. First and second isolation diffusion layers 23 and 24 are formed below the insulating isolation part 22, and the second isolation diffusion layer 24 is wider than the first isolation diffusion layer 23 in the first region A.

  • Publication number: 20110115955
    Abstract: An object of the present invention is to provide a solid-state image device that can effectively dissipate heat. In order to attain the object, the solid-state image device of the present invention includes non-through heat dissipation portions (7) provided on a semiconductor substrate (2). The non-through heat dissipation portion (7) is made up of a non-through hole and a metal embedded in the non-through hole. The non-through hole has one open end on one of the surfaces of the semiconductor substrate (2), extends from the one surface toward the other surface of the semiconductor substrate (2), and has the other end between the surfaces of the semiconductor substrate (2). The non-through heat dissipation portions (7) act as heat dissipation paths.
