Solid-state image sensor including patterned structure for decreasing petal flares

Abstract

A solid-state image sensor is provided. The solid-state image sensor includes a plurality of photoelectric conversion elements. The solid-state image sensor also includes a color filter layer disposed above the photoelectric conversion elements. The color filter layer has a plurality of color filter segments. The solid-state image sensor further includes a partition grid disposed between the color filter segments. Moreover, the solid-state image sensor includes a patterned structure disposed on the color filter layer. The patterned structure has a plurality of patterned segments. The solid-state image sensor also includes a transparent layer disposed on the color filter layer and the partition grid. The transparent layer surrounds the patterned segments. At least one patterned segment is disposed on the partition grid.
