Abstract
PURPOSE: To prevent the generation of a blooming phenomenon and to improve resolution and a degree of integration as a result, by providing a diffusion part, accepting excessive charge, on the opposite side to passages of a photoelectric conversion part and transfer parts.
CONSTITUTION: To form a well of a potential needed to acquire charge generated in accordance with the quantity of incident light on a boundary surface between the gate oxide film of photoelectric conversion part 25 and a semiconductor substrate, a DC voltage is applied to photo gate electrode 55 via terminal 56 during the photo signal storage time. At this time, charge generated according to the quantity of incident light is accumulated in each element of conversion part 25. Then, the DC voltage to terminal 56 is cut off and applied to shift gate parts 28 and 29 by way of terminals 59 and 60 to send accumulated charge in respective picture elements 30∼ 40 to transfer parts 26 and 27. Transfer parts are moved by pulses of driving pulse generating sources 65 and 66 to charge sent in this way and it is extracted from output terminals 63 and 64 via detection parts 61 and 62. Here, excessive charge never flows into any other converting element than passages to transfer part and overflow regions.
