Abstract:
A method for fabricating a semiconductor substrate is disclosed, which includes: forming a first dielectric layer on a substrate body; foil ling a plurality of first vias penetrating the first dielectric layer to expose portions of the substrate body; forming a second dielectric layer on the first dielectric layer and the exposed portions of the substrate body, wherein the second dielectric layer extends on walls of the first vias; etching the second dielectric layer to form a plurality of openings communicating with the first vias and form a plurality of second vias penetrating the second dielectric layer in the first vias so as to expose portions of the substrate body, leaving the second dielectric layer on the walls of the first vias; and forming a circuit layer in the openings, and forming a plurality of conductive vias in the second vias for electrically connecting the circuit layer and the substrate body.
