Abstract

The invention provides a processing method based on anisotropic homogenization of multiple isotropic materials, specifically selecting an equivalent volume element reasonably in a multi-embedded area of ​​a complex structure, and each material in the volume element is an isotropic material , the equivalent volume element is a new structure, and the specific parameters of the structure in various directions can be reacquired through experiments or simulations. Specifically, it can be summarized as applying force / heat loads to this volume element, and collecting the equivalent volume element ( The displacement / heat / force result data of RVE) can be calculated by the formula to obtain the anisotropic material properties of the equivalent volume element. The invention solves the problems that the equivalent volume method ignores the anisotropy of the whole module in different directions, which leads to large deviations in experimental values ​​and cannot simplify the processing of multi-layer nested packaging structures / materials in microelectronic products, and greatly improves the experimental value. The accuracy of the value can effectively improve the efficiency of reliability testing of microelectronic products and simplify the workflow.

Description

technical field

[0001] The invention belongs to the technical field of electronic manufacturing and packaging and testing, and in particular relates to a processing method based on anisotropic homogenization of multiple isotropic materials. Background technique

[0002] Over the past few decades, microelectronics technology has developed by leaps and bounds along Moore's Law. Integrated circuits are the main research object and representative products of microelectronics. The information industry based on integrated circuits has become the world's largest industry. Previously, we relied on continuously shrinking the device size to increase the relative area of ​​the wafer, realizing the continuous improvement of the performance of integrated circuit products in accordance with "Moore's Law". As the feature size of integrated circuits approaches the technological and physical limits, continuing Moore's Law becomes increasingly Difficult, but now with advanced packaging techno...
