Abstract:
A fabricating method for a semiconductor package, comprising the steps of:preparing a chip carrier; mounting at least one semiconductor chip on the chip carrier in a manner that a first surface of the chip is attached to a predetermined position on a second surface of the chip carrier; preparing a covering module plate consisting of at least one covering plate and sufficiently dimensioned for entirely covering the chip carrier, and forming an interface layer on a first surface of the covering module plate, wherein the interface layer is poor in adhesion to the chip and a molding compound used for forming an encapsulant, and has the adhesion to the chip and the molding compound smaller than that to the covering module plate; attaching the interface layer on the first surface of the covering module plate to a second surface opposing the first surface of the chip; performing a molding process; performing a ball implantation process; performing a singulation process; heating a singulated semi-fabricated semiconductor package; and removing the interface layer, the covering plate and a portion of the encapsulant formed on a second surface of the covering plate from the second surface of the chip and a portion of the encapsulant formed around the chip.
