Abstract:
A semiconductor package includes a first lead frame type having a first type of package leads and a pre-molded portion, and a second lead frame type having a second type of package leads that surround a die pad and are supported by the pre-molded portion. An integrated circuit is attached to the die pad and electrically connected to the first and second types of leads with bond wires. A mold compound, which forms a mold cap, covers the first and second lead frame types, the integrated circuit and the bond wires. The first lead frame type may be a QFP type and the second lead frame type may be a QFN type.
