Abstract

A solid-state imaging device includes: a semiconductor substrate; photoelectric conversion units formed in array on the semiconductor substrate and forming a light receiving unit; and wiring sections formed in positions among the photoelectric conversion units. The wiring sections include wiring bodies formed by superimposing wiring layers on the light receiving unit and including a bottom wiringbody on the semiconductor substrate side, a top wiring body on an uppermost side, and an intermediate wiring body between the bottom wiring body and the top wiring body, and contacts connecting the wiring bodies in order of vertical overlap, and in at least one of the wiring sections, the wiring bodies other than the bottom wiring body are superimposed while being shifted from a position right above the bottom wiring body, and amounts of shift of the intermediate wiring body and the contacts connected to the intermediate wiring body are the same.

Description

[0001] Cross References to Related Applications [0002] This application contains subject matter related to the disclosure of Japanese Priority Patent Application JP 2009-103176 filed in the Japan Patent Office on Apr. 21, 2009, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a solid-state imaging device and an imaging device including a wiring portion formed in a light receiving unit in which a plurality of photoelectric conversion units are arranged.
