Abstract
An embedded and packaged heat dissipation structure and a manufacturing method therefor, and a semiconductor are disclosed. The method includes: forming a first semi-finished plate; forming a heat dissipation plate based on the first metal layer; manufacturing a heat dissipation copper column on the heat dissipation plate; providing a dielectric layer; laminating a second metal layer on the dielectric layer; partially etching the second metal layer and the dielectric layer to form a microchannel; manufacturing a thin metal layer to enable an inner wall of the microchannel to form an isolation layer with an integrated structure to obtain a second semi-finished plate; manufacturing a first cover layer; and laminating the first cover layer and the second semi-finished plate to connect the first cover layer and the isolation layer in a sealed manner to obtain the embedded and packaged heat dissipation structure.
