METHOD FOR MANUFACTURING A THREE-DIMENSIONAL LTCC PACKAGE STRUCTURE

A method includes the steps of: a) providing an interposer, wherein the interposer has a chamber therein, multiple chip I/O contacts are formed in the chamber, and the chip I/O contacts are connected to connecting wires disposed in the interposer through transmission wires in the interposer; b) placing a semiconductor chip in the chamber and electrically connecting pins of the semiconductor chip to the chip I/O contacts; c) providing a substrate, wherein signal contacts and external contacts are disposed on two sides of the substrate, respectively, and the signal contacts are electrically connected to the external contacts through transmission wires embedded in the substrate; d) superposing the interposer on the substrate to form a combination, wherein the signal contacts of the substrate separately electrically connect with the connecting wires of the interposer; and e) encapsulating the combination with encapsulation adhesive.
