ABSTRACT:
Photoelectric transducing elements are formed in a first impurity-doped region (14), and signal charge reading-out circuits (2, 3) are formed in a second impurity-doped region which is deeper than the first impurity-doped region, so that fixed pattern noise is drastically reduced, improving picture quality.
