Abstract

An embodiment of the invention discloses a three-dimensional fan-out package structure. The structure comprises a first chip, one or more second metal columns, a second chip, a second insulation resin, and a re-wiring structure, wherein the one or more second metal columns are arranged at the periphery of the first chip, the second chip is formed by one or more chips, the second chip is stacked onthe back of the first chip, a surface pad of the second chip is electrically connected to the second metal column through a metal wire, the second insulation resin wraps the first chip, the second chip and the second metal columns, and the surface of a first metal column, the surface of a first insulation resin, the bottom surface of the second metal column and the bottom surface of the second insulation resin are flush with one another. The package structure disclosed in the invention has the advantages of small size and low cost.

Description

technical field [0001] The invention relates to the packaging field, in particular to an ultra-thin three-dimensional high-density fan-out packaging structure and a manufacturing method thereof. Background technique [0002] Three-dimensional integrated circuit packaging has many advantages, such as high packaging density and small footprint. There are various three-dimensional integrated circuit packaging structures and three-dimensional integrated circuit packaging methods in the prior art. [0003] Image 6 A schematic cross-sectional view of a prior art PoP (package on package) package structure is shown. The PoP package is fabricated by stacking two packages, including a top package 101 and a bottom package 102 , with a total thickness of approximately 1.4mm. Top package 101 contains stacked die 103 . The top package 101 and the bottom package 102 each contain a circuit board (circuit board thickness 0.3 mm) and a set of solder balls 104 (solder ball height 0.25 mm)....
