An image sensor comprising:
- a plurality of photodiodes arranged in first and second directions in a matrix;
- a plurality of first isolation layers, each two adjacent first isolation layers arranged in the first direction being spaced apart from each other by a first distance, each first isolation layer being interposed between adjacent photodiodes arranged in the second direction;
- and
- a plurality of second isolation layers, each two adjacent second isolation layers arranged in the second direction being spaced apart from each other by a second distance, each second isolation layer being interposed between adjacent photodiodes arranged in the first direction,
- wherein a space between two adjacent first isolation layers arranged in the first direction and a space between two adjacent second isolation layers arranged in the second direction overlap to form a blank region surrounded by the two adjacent first isolation layers and the two adjacent second isolation layers within a substrate including the first isolation layers and the second isolation layers.
