Abstract

PURPOSE:To obtain a picture element with high density by forming junction type overflow drain regions on separating regions which are used for separating transfer regions. CONSTITUTION:A plurality of N type transfer regions 22 which are partitioned by P type separating regions 21 are formed in a P type Si substrate 20. A shallow N type separating region 23 is formed in each region 22. A highly concentrated P<+> type overflow drain region 24 is formed corresponding to each region 23. In this constitution, a specific bias voltage is applied to the region 24 during the period of light receiving. When the overflow begins due to the excessive reception of the light during the light receiving period, the electric charges flow from one region 22 to the adjacent region 22. When the adjacent region 22 is overflowed, the excessive charges are absorbed by the region 24 as minority carriers, and a stable state is obtained. During the charge transfer period, the P-N junction is reversedly biased by raising the potential at the region 24 to the zero side, the potential at the region 23 is raised, and the right and left regions 22 are separated. Under this state, the signal charges can be excellently transferred.
