Abstract:
1. A semiconductor package, comprising: a substrate mounted with at least one semiconductor chip thereon and electrically connected to the semiconductor chip; and an encapsulant formed by a molding compound injected into a molding cavity of a mold for encapsulating the semiconductor chip mounted on the substrate, wherein the molding cavity is formed with a plurality of recess portions at corner positions thereof, and the recessed portions are dimensioned to be relatively smaller in height than the molding cavity and are each connected to an air vent formed in the mold for interconnecting the recess portions and outside of the mold, such that the encapsulant is formed with a plurality of outwardly-extending portions by the molding compound filled in the recess portions of the molding cavity, and the outwardly-extending portions are located in positions corresponding to the corner positions of the molding cavity.
