Abstract: 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.

Abstract: A solid-state image sensor includes a substrate, photoelectric conversion elements positioned on the substrate, a filter module positioned above the photoelectric conversion elements positioned on the substrate, lenses positioned above the filter module positioned above the photoelectric conversion elements, a resin layer formed such that the resin layer is surrounding an outer edge of the filter module positioned on the substrate, and an anti-reflection film formed on the lenses and resin layer such that the anti-reflection film has a peripheral film portion covering a peripheral portion of the resin layer. The filter module is positioned such that light is transmitted through the filter module before being incident on the photoelectric conversion elements, and the anti-reflection film is formed such that the peripheral film portion has an uneven shape having unevenness in thickness direction of the resin layer and at least part of an outer edge protruding outside the resin layer.
