Multi-chip semiconductor package
A multi-hip semiconductor package is proposed, in which a first chip and a second chip are mounted on opposing surfaces of a lead frame in a staggered manner. This staggered arrangement assures the die bonding quality for firmly disposing the second chip in the semiconductor package without being detrimental affected by the first chip. Moreover, as both opposing surfaces of the lead frame have chips mounted thereon, a mold flow of a molding resin used in a molding process can be balanced, so that turbulence the mold flow is decreased, and void formation can be avoided. In addition, the semiconductor package can incorporate a third chip in a stacked manner with respect to the first or second chip. This therefore further improves the functionality and performance of the semiconductor package.
