IPC: H04N5/369
Filed: 2001-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent color mixing, smear, and the like by limiting the move of a signal charge between adjacent photosensor sections. SOLUTION: An annular intralyer insulating film 100 for surrounding a lower- layer region of each photosensor section 120 is provided at the middle layer of a semiconductor substrate 110, thus setting the position of an overflow barrier 180 deeper at the lower-layer region of each photosensor section 120, and shallower at the surrounding region.
