Claim Text:
1. A method for forming a package structure, comprising: providing a pre-packaged panel comprising a first encapsulation layer, which comprises a plurality of integrating units arranged in a matrix form, wherein each of the integrating units comprises at least one semiconductor chip with a plurality of first pads, and the first encapsulation layer exposes the first pads and first metal bumps are disposed on the first pads; providing a circuit board comprising a first surface and a second surface opposite to the first surface, where the circuit board comprises a plurality of carrying units arranged in a matrix form, each of which comprises a plurality of input pads on the first surface and a plurality of output pads on the second surface, where the input pads and the output pads are interconnected electrically; mounting the pre-packaged panel on the first surface of the circuit board to form a plurality of package units arranged in a matrix form, where the integrating units of the pre-packaged panel one-to-one correspond to the carrying units of the circuit board, and the first metal bumps of the pre-packaged panel and the input pads on the first surface of the circuit board are respectively soldered together; forming a filling layer by filling a space between the first surface of the circuit board and the pre-packaged panel; forming second metal bumps on the output pads on the second surface of the circuit board; and cutting the structure based on the plurality of package units to form a plurality of independent package structures.
