Abstract:
A semiconductor device, comprising:a substrate having a first side and an opposing second side, and formed with an opening penetrating the substrate, wherein a plurality of conductive traces are disposed on the first side of the substrate; a chip having an active side and an opposing inactive side, and accommodated in the opening of the substrate, wherein the chip is dimensionally smaller in surface area than the opening; a plurality of first conductive elements for connecting the active side of the chip to the conductive traces on the substrate, so as to establish electrical connection between the chip and the substrate; a plurality of array-arranged second conductive elements disposed on the first side of the substrate, and electrically connected to the conductive traces on the substrate; and a first encapsulant formed on the first side of the substrate for encapsulating the chip, the first conductive elements, the second conductive elements and the conductive traces, in a manner that the inactive side of the chip and bottom sides of the second conductive elements are exposed to outside of the first encapsulant respectively, and the bottom sides of the second conductive elements are coplanarly positioned with a bottom side of the first encapsulant beneath the first side of the substrate.
