Abstract
The solid-state image sensor includes a semiconductor substrate having first and second photoelectric conversion elements, a color filter layer, and a hybrid layer. The isolation structure is disposed between the first and second photoelectric conversion elements. The color filter layer is disposed above the semiconductor substrate. The hybrid layer is disposed between the semiconductor substrate and the color filter layer. The hybrid layer includes a first partition structure, a second partition structure, and a transparent layer. The first partition structure is disposed to correspond to the isolation structure. The second partition structure is surrounded by the first partition structure. The transparent layer is between the first partition structure and the second partition structure. The refractive index of the first partition structure and the refractive index of the second partition structure are lower than the refractive index of the transparent layer.
