Abstract

The invention provides a modular packaging structure and method. The modular packaging structure comprises: at least one first module arranged in a stacked manner, each comprising a first chip and a second chip arranged opposite to each other, the first chip being electrically led out to a first surface and / or a second surface of the first module, and the second chip being electrically led out tothe first surface and / or the second surface of the first module; and a second module which is attached to the first module and comprises a third chip, wherein the third chip is electrically led out tothe first surface and / or the second surface of the second module, and the second module is electrically connected with the first module.

Description

technical field [0001] The invention relates to the technical field of semiconductor packaging, in particular to a modular packaging structure and method. Background technique [0002] The existing preparation method of heterogeneous substrate integrated structure generally uses multi-layer heterogeneous substrate and organic metal wiring layer for line layout and signal interconnection, and then pastes multiple functional chips on one side, and realizes three-dimensional structure through space folding. 3D integration. Due to the use of multi-layer heterogeneous substrates and organic metal wiring layers in this method, the size in the Z direction will be very large after three-dimensional folding. For the small size currently required, the X and Y directions will be reduced while the Z direction will be greatly increased. The size and thickness of the above cannot effectively reduce the package volume of the structural parts and improve the integration of the microsystem....
