Abstract
Through heat discharge only by wiring connected to a conventional semiconductor chip, sufficient heat discharge performance may not be achieved in a recent semiconductor device. A semiconductor device according to an aspect of the present invention includes: a flexible substrate including a first main surface and a second main surface; a semiconductor chip; a first heat conductive layer formed on the first main surface of the flexible substrate and electrically connected to the semiconductor chip; and a second heat conductive layer formed on the second main surface of the flexible substrate and electrically insulated from the semiconductor chip.
