Abstract
An imaging apparatus comprises a semiconductor substrate, a photoelectric converter, a charge storage region, and an amplification transistor. The photoelectric converter includes a pixel electrode, a counter electrode, and a photoelectric conversion layer. The photoelectric conversion layer is positioned above the semiconductor substrate and is disposed between the pixel electrode and the counter electrode. Charge generated by the photoelectric converter is stored in the charge storage region. The amplification transistor includes a source, a drain, and a gate electrode. The gate electrode is electrically connected to the charge storage region. In a plan view, the width of the drain of the amplification transistor is less than the width of the source of the amplification transistor.
