Patent ID: 8026580

Claim:
A semiconductor device package comprising: a lead frame having a plurality of spaced contact areas; at least a first and second semiconductor die coplanar with one another and each having at least one contact on one surface thereof, said contact of each of said die being electrically and mechanically connected to a respective one of said plurality of spaced contact areas of said lead frame, the tops of said first and second die being at least approximately coplanar; and a conductive heat spreader fixed to a peripheral area of said lead frame and forming a volume atop said lead frame, which volume contains said at least first and second die, the interior surface of said conductive heat spreader being parallel to said tops of said first and second die and being closely spaced apart from said tops of said first and second die by a gap of said volume, but insulated from said first and second die and permitting effective heat transfer from the die to the heat spreader; said conductive heat spreader including one or more openings allowing access to an entirety of said volume; and said lead frame and said conductive heat spreader providing two sided cooling for said at least first and second die.
