Abstract
An electronic device includes a carrier wafer having a front side and a back side, with an electrical connection network configured to connect the front side to the back side. An electronic chip is mounted on the front side of the carrier wafer and electrically connected to front pads of the electrical connection network. A sheet of a thermally conductive graphite or a pyrolytic graphite is added to the back side of the carrier wafer. The sheet includes apertures which leave back pads of the electrical connection network uncovered.
