Abstract
An image sensor includes a semiconductor substrate having a plurality of pixel regions arranged in a first direction and a second direction that are parallel to an upper surface of the semiconductor substrate. The first direction is perpendicular to the second direction. A grid structure extends in the first direction and the second direction on the semiconductor substrate to define openings corresponding to a plurality of sub-pixel regions of the plurality of the pixel regions, respectively. Color filters are disposed in the openings of the grid structure, respectively. A protective layer covers sidewalls of the grid structure and bottom surfaces of the color filters. The protective layer includes silicon oxide including carbon (C) or nitrogen (N).
