Abstract
An image sensor includes a semiconductor substrate having first and second surfaces facing each other and a first device isolation layer provided in the semiconductor substrate. The first device isolation layer defines pixel regions of the semiconductor substrate and includes first and second portions crossing each other. The first and second portions are provided to surround one of the pixel regions, and the first portion is provided to extend from the first surface of the semiconductor substrate toward the second surface and to have a structure inclined relative to the first surface.
