Claim 5:
6. A semiconductor assembly, comprising:
a circuit board;
a molded semiconductor package on the circuit board and comprising:
a mold compound having a bottom main surface facing the circuit board and a top main surface opposite the bottom main surface;
a plurality of leads, each lead of the plurality of leads having a first end embedded in the mold compound and a second end protruding from a side face of the mold compound and attached to a first main surface of the circuit board; and
a semiconductor die embedded in the mold compound and electrically connected, within the mold compound, to the plurality of leads,
wherein the second end of each lead of the plurality of leads has a bottom surface facing the circuit board,
wherein each lead of the plurality of leads has a negative standoff relative to the bottom main surface of the mold compound so that no lead of the plurality of leads is positioned closer to the circuit board than the mold compound;

a cooling structure disposed over the top main surface of the mold compound; and
a thermal interface material filling a gap between the top main surface of the mold compound and the cooling structure,
wherein the thermal interface material has a thickness of 100 μm or less.
