ABSTRACT:
A solid state image sensing device comprises photoelectric converting portions (8) and charge coupled portions. A plurality of parallel trenches (2) are formed on a main surface of a semiconductor substrate (1). Photoelectric converting portions are on the surfaces of the semiconductor substrate on both sides of each of the trenches. Charge transfer portions corresponding to the photoelectric converting portions are independently formed on the side surfaces of the trenches. Insulating and isolating regions (15, 29, 30) are formed on the bottom portions of the trenches. By providing two independent charge transfer portions in one trench, the area occupied by the charge transfer portions can be reduced.
