Abstract:
A low-profile semiconductor device, comprising:a substrate having a base layer and a plurality of conductive traces formed on the base layer, the base layer being formed with at least a hole;a semiconductor die having an active surface and an opposing inactive surface, the semiconductor die being mounted on the base layer of the substrate via the active surface thereof;a plurality of first conductive elements passing through the hole in the substrate for electrically coupling the semiconductor die to the conductive traces on the substrate;a plurality of second conductive elements arranged on terminals of the conductive traces for electrically connecting the semiconductor die to external devices;a fist encapsulant formed on the substrate to encapsulate the semiconductor die; anda second encapsulant formed over the conductive traces of the substrate so as to encapsulate the conductive traces, the first conductive elements and the hole; wherein the second encapsulant is formed in such a manner that the second conductive elements are encapsulated by the second encapsulant with bottom ends of the second conductive elements being exposed to and flush with a bottom surface of the second encapsulant.
