Abstract
A method of manufacturing a solid-state image sensor is provided. A first insulating member and an electrically conductive member is formed above a semiconductor substrate. A connecting portion of an upper surface of the electrically conductive member is covered with part of the first insulating member. First openings corresponding to the photoelectric conversion units are formed in the first insulating member. A second insulating member covering the first insulating member is then formed. The second insulating member is partially removed to expose the part of the first insulating member covering the connecting portion. A third insulating member that covers the first and second insulating members is then formed. The third insulating member is partially removed to expose the second insulating member. A second opening to expose the connecting portion is then formed to form a plug.
