ABSTRACT:
A source region and drain region are formed in a surface region of a first semiconductor region. Moreover, a second semiconductor region connected to the drain region is formed in the surface region of the first semiconductor region. A third semiconductor region is formed in the first semiconductor region under the second semiconductor region, connected to the second semiconductor region, and accumulates signal charges in accordance with an incident light. A fourth semiconductor region is formed in the surface region of the first semiconductor region between the drain region and source region. Moreover, these source region, drain region, second semiconductor region, and third semiconductor region constitute a pixel, and different voltages are supplied to the drain region in an accumulation period of the signal charges in the pixel, signal readout period, and discharge period of the signal charges.
