Abstract
A solid-state image pickup device for preventing crosstalk between adjacent pixels by providing an overflow barrier at the deep potion of a substrate. A partial P type region is provided at the predetermined position of a lower layer region of the vertical transfer register and a channel stop region. This P type region adjusts potential in the lower layer region of the vertical transfer register and the channel stop region. Accordingly, since the potential in the lower layer region of the vertical transfer register and the channel stop region at both sides of the lower layer region is low, electric charges photoelectrically-converted by the sensor region are blocked by this potential barrier and cannot be diffused easily.
