Abstract:
1. A semiconductor device, comprising: a semiconductor substrate in which a metal-oxide-semiconductor field-effect transistor (MOSFET) is formed; a dielectric layer, provided on the semiconductor substrate and covering the MOSFET, wherein a plurality of interconnection structures are formed in the dielectric layer; and at least one heat dissipation path, embedded in the dielectric layer between the interconnection structures, for liquid or gas to circulate in the heat dissipation path, wherein openings of the heat dissipation path are exposed on the surface of the dielectric layer; wherein the heat dissipation path comprises a plurality of interconnected trenches embedded in the dielectric layer between the interconnection structures and the heat dissipation path further comprises a micro heat dissipation pipe provided in the trenches, and the micro heat dissipation pipe is adapted for liquid or gas to circulate therein; wherein dielectric materials are filled in the trenches outside the micro heat dissipation pipe.
