Abstract
Technology that achieves high integration of a semiconductor device employing TSV technology is provided. A through electrode is configured by a small-diameter through electrode having a first diameter and being formed on a main surface side of a semiconductor wafer, and a large-diameter through electrode having a second diameter larger than the above-described first diameter and being formed on a back surface side of the semiconductor wafer, and the small-diameter through electrode is arranged inside the large-diameter through electrode in a planar view so that a center position of the small-diameter through electrode and a center position of the large-diameter through electrode do not overlap with each other in the planar view.
