1. A semiconductor device, comprising;

  • a substrate including a plurality of layers, an inner portion having at least one inner layer, a concave area exposing an inner ground layer of the substrate, a first side and a second side opposing the first side;

    a plurality of vacant thermal via holes formed in the inner ground layer of the substrate, the thermal via holes intersecting a conductor pattern of at least one layer of the substrate;

    an electronic component mounted over the thermal via holes on the first side of the substrate;

    a bonding agent attaching the electronic component to a surface of the inner ground layer;

    a heat discharging element disposed on the second side of the substrate; and

    a high heat conductive material located between the heat discharging element and the substrate and adjacent the thermal via holes.
