Semiconductor device and stacked semiconductor device that can increase flexibility in designing a stacked semiconductor device

摘要

A semiconductor device includes a semiconductor element having a plurality of electrodes provided on one principal surface thereof and a wiring substrate having a conductive layer on an insulating substrate. The wiring substrate is arranged in a substantially U-shape along an outer edge of the semiconductor element. An end of the conductive layer of the wiring substrate is connected to the electrodes of the semiconductor element. The other end of the conductive layer extends in a direction opposite to the semiconductor element on the other principal surface side of the semiconductor element.
