Embodiment Construction

[0024] The first set of examples

[0025] Next refer to Figure 1A and 1B A first group of embodiments of the present invention will be described. For ease of description, in Figure 1A and 1B In , only the wiring lines related to the first group of embodiments are shown. Actually, in order to operate the image pickup device, a plurality of wiring lines are also provided. For example, gate control lines of transistors and signal output lines supplied to each of pixel rows are provided.

[0026] According to a first set of embodiments of the present invention, an image pickup device includes a plurality of photoelectric conversion units arranged in a two-dimensional array. A region in which a plurality of photoelectric conversion units are disposed serves as an image sensing region. For example, a photodiode (hereinafter simply referred to as “PD”) is used as the photoelectric conversion unit. The PD includes an N-type (first conductivity type) semiconductor region and ...

Abstract

An image pickup apparatus according to one or more embodiments includes a power line and first through fourth photodiodes. The first, second, and third photodiodes are arranged along a first direction so that the first photodiode is adjacent to the second photodiode, and the second photodiode is adjacent to the third photodiode. The power line includes a first conductor disposed along the first direction and a second conductor disposed along a second direction that intersects the first direction. The second conductor is disposed on a region between the second and third photodiodes. First and second transistors corresponding to the first and second photodiode, respectively, are connected to the power line. The fourth photodiode is disposed adjacent to the second photodiode in the second direction. A third transistor corresponding to the fourth photodiode is connected to the power line.

Description

technical field [0001] The present invention relates to an image pickup device and an image pickup system. Background technique [0002] An image pickup device including a plurality of photoelectric conversion units arranged in a two-dimensional array is used in, for example, a digital camera and a digital camcorder. [0003] A technique for detecting a focus state using a phase difference method is used in an image pickup device. Japanese Patent Laid-Open No. 2001-250931 describes an image pickup device including two photoelectric conversion units under each of a plurality of microlenses to receive light rays divided from light rays gathered by the microlenses. The photoelectric conversion unit is configured to receive light from different pupil planes of the image capture lens. [0004] As in Japanese Patent Publication No. 2001-250931 Figure 8 As shown in , in the image pickup device, each of the two photoelectric conversion units provided under the microlens has a tra...
