Abstract
An apparatus includes a pixel region having disposed therein in a matrix form a plurality of conversion components, an amplifier transistor which amplifies a signal from the plurality of conversion components, a reset transistor which sets the potential of an input portion of the amplifier transistor to a reset potential, and a select transistor which is connected in series to the amplifier transistor and selects and reads the amplified signal, and well contact regions which are provided within the pixel region. Each of the well contact regions is neighboring to a drain region of the reset transistor, and the drain region of the reset transistor has a lower impurity concentration than the impurity concentration in the source and drain regions of the select transistor.
