ABSTRACT:
A multi-chips module assembly package mainly comprises a first package, a second package and an intermediate substrate. The intermediate substrate includes an opening, at least a via and a plurality of circuit layers, wherein the second package is accommodated in the opening. The via has an inner wall, and a plurality of separated electrically conductive layers, which is formed on the inner wall and connected with the corresponding circuit layers. The first package electrically connects with the second package through the intermediate substrate, and the intermediate substrate is interposed between the first package and the second package. At least an insulator is formed in the via, and the separated electrically conductive layers are separated from each other. After the intermediate substrate is interposed between the first package and the second package, there will be not enough space between the intermediate substrate, the first package and the second package for disposing conductive devices therein. Therefore, the first package will be electrically connected to the second package through the separated electrically conductive layers of the intermediate substrate for providing more conductive devices disposed and interposed between the intermediate substrate, the first package and the second package.
