IMAGING APPARATUS AND IMAGING SYSTEM

摘要

One embodiment is an imaging apparatus including multiple pixels. The pixels include first and second photoelectric conversion units, a floating diffusion portion, and first and second transfer transistors configured to transfer electric carriers generated at the respective first and second photoelectric conversion units to the floating diffusion portion. The imaging apparatus includes a first conductive member electrically connected to the gate electrode of the first transfer transistor, a second conductive member electrically connected to the gate electrode of the second transfer transistor, and a control unit. The distance of closest proximity between the first conductive member and the floating diffusion portion is shorter than distance of closest proximity between the second conductive member and the floating diffusion portion.

1. An imaging apparatus comprising:
a plurality of pixels including at least a first photoelectric conversion unit, a second photoelectric conversion unit, a floating diffusion portion, a first transfer transistor configured to transfer an electric carrier generated at the first photoelectric conversion unit to the floating diffusion portion, and a second transfer transistor configured to transfer an electric carrier generated at the second photoelectric conversion unit to the floating diffusion portion; a first conductive member electrically connected to a gate electrode of the first transfer transistor; a second conductive member electrically connected to a gate electrode of the second transfer transistor; and a control unit electrically connected to the first transfer transistor and the second transfer transistor via the first conductive member and the second conductive member respectively; wherein a distance of closest proximity between the first conductive member and the floating diffusion portion is shorter than a distance of closest proximity between the second conductive member and the floating diffusion portion; and wherein the control unit is configured to perform: a first control operation for turning on the first transfer transistor from a state in which both of the first transfer transistor and the second transfer transistor are off, while keeping the second transfer transistor off, and a second control operation for setting the first transfer transistor and the second transfer transistor being on in parallel with each other in a state in which an electric carrier transferred by the first control operation is held at the floating diffusion portion.
