SOLID-STATE IMAGE SENSOR

A solid-state image sensor including a wafer substrate including photoelectric conversion elements, a filter module formed over the wafer substrate and including different color filters each aligned with a different one of the photoelectric conversion elements, each of the color filters being formed in a different one of color filter regions, and a microlens module including microlenses each aligned with a different one of the color filters. The microlens module includes main lenses each formed within a corresponding one of the color filter regions in a plan view, and auxiliary lenses formed in different corner portions of the color filter regions, and having a lens parameter different from a lens parameter of the main lenses.
