Abstract
A semiconductor device comprising a thermally conductive foil including a chip mount portion having first and second surfaces; an integrated circuit chip attached to said first surface; a body of encapsulation material molded around said chip and said first surface such that it leaves said second surface exposed; and said second surface comprising means for forming thermal contact, thereby creating a path for dissipating thermal energy from said chip. Said means for thermal contact comprise a configuration of said second surface suitable for direct thermal attachment to a heat sink. Alternatively, said means for thermal contact comprise a configuration of said second surface suitable for thermal attachment including solder balls between the chip and the heat sink.
