Claim:
1. An electronic component, comprising: one or more semiconductor dice that forms at least one transistor device, embedded in a first dielectric layer; a heat-spreader embedded in a second dielectric layer, wherein the heat-spreader has a higher thermal conductivity in directions substantially parallel to the major surface of the one or more semiconductor dice than in directions substantially perpendicular to the major surface of the one or more semiconductor dice, and a heat-sink thermally coupled to the heat-spreader, wherein the one or more semiconductor dice form a half-bridge circuit, and wherein the heat-spreader comprises a first metal foil, a second metal foil and graphite particle arranged between the first and second metal foil and metal filled blind vias introduced in at least one of the first metal foil and the second metal foil.
