摘要:
A semiconductor device includes: a semiconductor substrate including a first face and a second face on a side opposite to the first face; an external connection terminal formed on the first face of the semiconductor substrate; a first electrode formed on the first face of the semiconductor substrate and electrically connected to the external connection terminal; an electronic element formed on or above the second face of the semiconductor substrate; a second electrode electrically connected to the electronic element and having a top face and a rear face; a groove portion formed on the second face of the semiconductor substrate and having a bottom face including at least part of the rear face of the second electrode; and a conductive portion formed in the groove portion and electrically connected to the rear face of the second electrode.
