Abstract:
A solid-state image sensor includes: a pixel array that includes first pixels, each having first and second photoelectric conversion units, and second pixels, each having third and fourth photoelectric conversion units; first to fourth transfer gates via which a signal charge respectively generated in the first to fourth photoelectric conversion units is respectively transferred to first to fourth charge voltage conversion units. At least one of a gate width, a gate length and an installation position of at least one transfer gate among the first to fourth transfer gates is altered to achieve uniformity in voltage conversion efficiency at the first to fourth charge voltage conversion units.

Claim (Index 1):
A solid-stare image sensor, comprising:\n a pixel array that includes first pixels, each having a first photoelectric conversion unit and a second photoelectric conversion unit arranged along a first direction, and second pixels, each having a third photoelectric conversion unit and a fourth photoelectric conversion unit arranged along a second direction; a first transfer gate via which a signal charge generated in the first photoelectric conversion unit is transferred to a first charge voltage conversion unit; a second transfer gate via which a signal charge generated in the second photoelectric conversion unit is transferred to a second charge voltage conversion unit; a third transfer gate via which a signal charge generated in the third photoelectric conversion unit is transferred to a third charge voltage conversion unit; and a fourth transfer gate via which a signal charge generated in the fourth photoelectric conversion unit is transferred to a fourth charge voltage conversion unit, wherein: at least one of a gate width, a gate length and an installation position of at least one transfer gate among the first transfer gate, the second transfer gate, the third transfer gate and the fourth transfer gate is altered so as to achieve uniformity in voltage conversion efficiency at the first charge voltage conversion unit, the second charge voltage conversion unit, the third charge voltage conversion unit and the fourth charge voltage conversion unit.
