| 摘要 |
A semiconductor device according to an embodiment of the present invention includes a semiconductor chip. The semiconductor chip includes a semiconductor substrate, an interconnect layer, a back electrode (first working electrode), and a back dummy electrode (first dummy electrode). On the semiconductor substrate, the interconnect layer including an interconnect is provided. On a back surface of the semiconductor substrate, the back electrode is provided in electrical connection to the interconnect. On the back surface, also the back dummy electrode is provided, which is electrically insulated from the interconnect.
