Abstract

See full text

According to one embodiment, a semiconductor device includes: a semiconductor substrate, the semiconductor substrate having first and second surfaces; conductive regions extending in a direction from the first surface side toward the second surface side of the semiconductor substrate, the conductive regions including first and second vias; a first semiconductor region surrounding a part of each of the conductive regions on the second surface side of the semiconductor substrate, a portion other than a front surface of the first semiconductor region being surrounded by the semiconductor substrate; a first electrode provided on the second surface side; second electrodes provided on the first surface side, one of the second electrodes being in contact with one of the conductive regions; and an insulating film provided between each of the conductive regions and the semiconductor substrate, and between each of the conductive regions and the first semiconductor region.
