Abstract

The present invention discloses a heat radiation structure based on a graphene thermal interface layer. The structure comprises: multiple graphene layers, wherein each graphene layer has thickness andthe same length and width; multiple bonding layers, wherein each bonding layer has a thickness and one length and one width being the same as these of the graphene layers, the bonding layers and thegraphene layers alternatingly form a stacked structure, the stacked structure is subjected to spiral turning by taking a width direction as a shaft in a length direction starting from one end of the stacked structure to form a cylindrical spiral coil, the top surface and the bottom surface of the spiral coil are planes formed by spiral turning of two opposite thickness surfaces of the multiple graphene layers and the multiple bonding layers. The efficient heat radiation packaging structure based on the graphene thermal interface layer and the manufacturing method thereof effectively utilize graphene high-surface inner thermal conductivity and achieve efficient heat radiation packaging.

Description

technical field [0001] The invention relates to the technical field of integrated circuit packaging, in particular to a high-efficiency heat dissipation packaging structure based on a graphene thermal interface layer and a manufacturing method thereof. Background technique [0002] With the continuous development of integrated circuit technology, the performance of integrated circuit chips is constantly improving. The heat dissipation problem of high-integration, high-performance, and high-power chips is becoming more and more important. The rise of chip temperature will affect the performance of devices. work performance, shorten the working life of the device, and even cause direct damage to the device due to high temperature. [0003] The heat dissipation design in packaging technology is directly related to the heat dissipation effect of the overall chip system. The purpose of the heat dissipation design is to obtain a lower operating temperature and an effective heat di...
