Abstract
According to one embodiment, a semiconductor device includes a support and a stacked body on the support. The stacked body is formed of a plurality of semiconductor chips that are stacked on each other. The stacked body has a lower surface facing the support and an upper surface facing away from the support. A first wire is connected to one of the semiconductor chips in the stack and extends upward from the semiconductor chip to at least the height of the upper surface of the stacked body. A second wire is connected to the support and extends upward from the support to at least the height of the upper surface of the stacked body.
