Patent ID: 7557390

Claim:
A solid image capturing element, comprising: a plurality of vertical shift registers arranged to each column of a plurality of light receiving pixels in a matrix arrangement, a horizontal shift register provided on an output side of the plurality of vertical shift registers, and an output section provided on an output side of the horizontal shift register, wherein a semiconductor region of a first conductive type is formed closest to a shift register-side surface of a semiconductor substrate of the first conductive type, while a semiconductor region of a second conductive type which is different from the first conductive type is formed in a portion farther from the shift register-side surface than the semiconductor region of the first conductive type, and a first semiconductor region and a second semiconductor region having a higher dopant concentration than that of the first semiconductor region are formed in the semiconductor region of the second conductive type, the horizontal shift register is formed above the first semiconductor region; and the output section is formed above the second semiconductor region.
