Abstract: The present disclosure provides a chip packaging structure and method, using a back-to-back packaging structure, and realizing electrical connection between chips through TSV holes or cooperation between TSV and TMV holes, completely penetrating two chips. Thus, the TSV hole passing through a silicon material may not need to be formed in advance on the chips before bonding the chips, thereby the requirement of alignment accuracy of the chips can be reduced, and the process difficulty can be reduced. In addition, as the back-to-back packaging process is adopted, the heat dissipation efficiency of the chips can be improved, and the problem of circuit breakage due to materials with different expansion coefficients present between the chips can be avoided.
