Method of fabricating a three-dimensional system-on-chip and its structure

摘要

A three-dimensional system-on-chip structure comprises a plurality of chips and a plurality of plugs respectively fabricated in the chips. The chips are stacked on top of each other and each includes a periphery circuitry region. A plurality of contact pads is fabricated in each of the periphery circuitry regions. The plugs are formed in the corresponding stacked chips, and are electrically connected to the corresponding contact pads of two of the corresponding chips which are adjacent to each other, or two of the corresponding chips which are not adjacent to each other.
