Patent ID: 8106984

Claim:
A solid-state image capturing apparatus comprising a pixel array in which a plurality of pixels are arranged in a matrix, wherein each of the pixels includes: a photodiode for obtaining a signal charge by a photo-electric conversion of an incident light, a selection transistor for selecting a pixel that the selection transistor configures from the plurality of pixels that configure the pixel array, an amplifying transistor for amplifying the signal charge obtained at the photodiode, a transfer transistor for transferring the signal charge obtained at the photodiode to a gate electrode of the amplifying transistor, and a reset transistor for discharging the signal charge obtained at the photodiode, wherein the amplifying transistor is configured in such a manner that a gate area of the amplifying transistor is defined to be larger than a gate area of the other transistors that configure the pixel with the exception of the transfer transistor; the selection transistor is located in the same active area as that of the amplifying transistor, and a gate area of the selection transistor is defined to be equal to a gate area of the reset transistor or to be smaller than the gate area of the reset transistor; and the pixel array is configured in such a manner that a plurality of two adjacent pixels share the reset transistor, and the gate area of the reset transistor is defined to be an area of a region in which a gate electrode and a channel area of the gate electrode in the reset transistor are overlapped.
