Abstract
To improve an integration degree of a semiconductor device. The semiconductor device includes a plurality of wiring layers formed on the semiconductor substrate, a pad electrode formed on an uppermost wiring layer among the plurality of wiring layers, a base insulating film having a pad opening above the pad electrode, and a rewiring electrically connected to the pad electrode and extending over the base insulating film. Further, the semiconductor device includes a protective film covering an upper surface of the rewiring and having an external pad opening exposing part of the upper surface of the rewiring, an external pad electrode electrically connected to the rewiring through the external pad opening and extending over the protective film, and a wire connected to the external pad electrode. Part of the external pad electrode is located in a region outside the rewiring.
