Abstract

The invention discloses a chip packaging structure, comprising: a substrate; A heat dissipation layer arranged on one side surface of the substrate; A wafer disposed on a side of the heat dissipationlayer remote from the substrate; The shielding structure is fixedly mounted on the substrate and covers the periphery of the wafer, and a cavity is formed between the shielding structure and the wafer. The chip packaging structure of the invention has good heat dissipation performance, safety and reliability. At that same time, by provide a shielding structure, which can not only protect the circuit structure on the surface of the wafer, At the same time, the shielding structure has the ability of anti-electromagnetic interference, which can effectively prevent the chip packaging structure from being disturbed by electromagnetic waves in the work, ensure the stability of the control system of the chip packaging structure, and improve the use safety of the chip packaging structure.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a chip packaging structure and method. Background technique [0002] Due to the rapid development of the semiconductor industry, the power consumption of semiconductor chips continues to increase in order to meet system requirements, and heat dissipation becomes more and more difficult. At the same time, as the semiconductor industry has risen to a national strategic level, new challenges have been raised to the security performance of chips. At present, chip heat dissipation and safety performance determine the reliability of the chip. When the system is running at full capacity, if the chip cannot dissipate heat in time or the safety performance is unreliable, the related system will shut down, and in severe cases, it will cause immeasurable consequences. Contents of the invention [0003] The main purpose of the present invention is to provide a chip packaging structur...
