Abstract:
1. An imaging apparatus comprising: a plurality of unit cells each including a first photoelectric conversion unit, a second photoelectric conversion unit, a first transfer transistor configured to transfer an electric charge in the first photoelectric conversion unit, a second transfer transistor configured to transfer an electric charge in the second photoelectric conversion unit, and at least one transistor shared by the first and second photoelectric conversion units; a first conductive member electrically connected to gates of the plurality of first transfer transistors; a second conductive member electrically connected to gates of the plurality of second transfer transistors; a third conductive member disposed adjacently to the first conductive member in a same wiring layer as the first conductive member and electrically connected to a plurality of nodes each included in respective one of the plurality of unit cells; and a fourth conductive member disposed adjacently to the second conductive member in a same wiring layer as the second conductive member, wherein an opposing length of the first conductive member and the third conductive member in a wiring layer having the first and third conductive members is longer than an opposing length of the second conductive member and the fourth conductive member in a wiring layer having the second and fourth conductive members; and a width W1 of the first conductive member, a distance D1 between the first conductive member and the third conductive member in the wiring layer having the first and third conductive members, a width W2 of the second conductive member and a distance D2 between the second conductive member and the fourth conductive member in the wiring layer having the second and fourth conductive members satisfy a relationship of W1×D1>W2×D2.
