A solid-state image sensor is provided. The solid-state image sensor includes photoelectric conversion elements. The solid-state image sensor also includes a mosaic pattern layer disposed above the photoelectric conversion elements. The mosaic pattern layer includes an infrared-passing segment and color filter segments disposed on the periphery of the infrared-passing segment. The solid-state image sensor further includes a first condensing structure disposed on the mosaic pattern layer. The infrared-passing segment and the color filter segments share the first condensing structure.

Solid-state image sensor

An optical element is provided. The optical element includes a substrate; a plurality of metal grids formed on the substrate; an oxide layer formed on the substrate between the plurality of metal grids; and a plurality of organic layers formed on the plurality of metal grids, wherein the width of the organic layer is greater than the width of the metal grid, and there is at least one gap between the organic layer and the oxide layer.

Optical elements

A method for fabricating an optical element is provided. A substrate is provided. A plurality of metal grids are formed on the substrate. An organic layer is formed on the substrate and the metal grids. The organic layer is etched to form a first patterned organic layer including a plurality of first protrusion portions and a plurality of first trenches surrounded by the first protrusion portions. The first patterned organic layer is etched to form a second patterned organic layer including a plurality of second protrusion portions and a plurality of second trenches surrounded by the second protrusion portions. Each second protrusion portion covers one metal grid. There is a distance between the center axis of one second protrusion portion of the second patterned organic layer and the center axis of one metal grid covered by the one second protrusion portion of the second patterned organic layer.

Optical elements and method for fabricating the same

A method for fabricating an optical element is provided. The fabrication method includes the following steps. A substrate is provided. A plurality of metal grids are formed on the substrate. A first organic layer is formed on the substrate between the plurality of metal grids. A second organic layer is formed on the first organic layer and the plurality of metal grids. The second organic layer and the first organic layer are etched to leave the plurality of metal grids and a plurality of patterned second organic layers on the plurality of metal grids. An optical element fabricated by the method is also provided.
