Abstract:
A module device of stacked semiconductor packages, comprising:a first semiconductor package; and at least a second semiconductor package stacked on and electrically connected to the first semiconductor package; wherein the first semiconductor package comprises: a chip carrier; at least a chip mounted on the chip carrier; a plurality of first conductive elements for electrically connecting the chip to the chip carrier; a circuit board having a top surface and a bottom surface, and mounted above the chip; a plurality of second conductive elements disposed on the bottom surface of the circuit board, for supporting and electrically connecting the circuit board to the chip carrier; an encapsulant formed between the chip carrier and the circuit board, for encapsulating the chip and the first and second conductive elements, such that the encapsulant is flush with the top surface of the circuit board, allowing the top surface of the circuit board to be exposed to outside of the encapsulant and electrically connected with the second semiconductor package; and a plurality of third conductive elements for electrically connecting the first semiconductor package to an external device.
