Abstract

The invention provides a system-in-package method and structure of a heterogeneous integrated chip. The method comprises the steps: enabling bottom surfaces of a plurality of substrate chips to be pasted on slide glass, and forming a first integrated adapter plate; forming a first plastic package layer on the first integrated adapter plate, wherein the substrate chip and the first plastic packagelayer form a first plastic package body; performing a mechanical or chemical polishing process on a top of the first plastic package body to expose electric lead-out parts of the plurality of substrate chips; manufacturing a metal interconnection layer and a dielectric layer on the top surfaces of the plurality of substrate chips, wherein the metal interconnection layer is electrically connected with the electric lead-out parts of the plurality of substrate chips; connecting the plurality of heterogeneous chips to the first integrated adapter plate to form a second integrated adapter plate; performing a mechanical or chemical polishing process on the top of the second integrated adapter plate to enable absolute heights of the plurality of heterogeneous chips to be the same; and removing the first plastic package body from the slide glass.

Description

technical field [0001] The invention relates to the technical field of semiconductor packaging, in particular to a system-level packaging method and structure of a heterogeneous integrated chip. Background technique [0002] With 5G, artificial intelligence (AI), automotive electronics, Internet of Things (IoT), high-efficiency computing (HPC) and other new semiconductor application fields blooming, advanced wafer manufacturing processes are moving towards 7, 5, and 3nm, but as Moore's Law gradually Approaching the physical limit, one of the best ways to prolong the life of Moore's Law is advanced packaging technology, including fan-out wafer-level packaging (FOWLP), 2.5D / 3DIC packaging, and going further into 3D wafer stack packaging capable of heterogeneous integration. SiP packaged modules that meet the needs of heterogeneous integration are bound to have greater energy requirements. [0003] Through-silicon via technology (TSV) realizes the vertical interconnection betw...
