Abstract:
The invention provides an interposer substrate and a method of fabricating the same. The method includes: etching a carrier to form a recessed groove thereon; filling a dielectric material in the recessed groove to form a first dielectric material layer, or forming a patterned first dielectric material layer on the carrier; forming a first wiring layer, a first conductive block and a second dielectric material layer on the carrier and the first dielectric material layer sequentially, with the first wiring layer and the first conductive block embedded in the second dielectric material layer; and forming a second wiring layer and a second conductive block on the second dielectric material layer. A coreless interposer substrate having fine pitches is thus fabricated.

Claim (Index 1):
A method of fabricating an interposer substrate, comprising:\n forming on a carrier a first dielectric material layer having a plurality of openings, from which the carrier is exposed; forming a first wiring layer on the carrier, wherein a position of the first wiring layer corresponds to the plurality of openings of the first dielectric material layer; forming a plurality of first conductive blocks on the first wiring layer; covering the first wiring layer and the first conductive blocks with a second dielectric material layer, with terminal portions of the first conductive blocks exposed from the second dielectric material layer; forming on the second dielectric material layer a second wiring layer electrically connected with the first conductive blocks; forming a plurality of second conductive blocks on the second wiring layer; and forming an insulative protection layer on the second dielectric material layer, the second wiring layer and the second conductive blocks, from which the second conductive blocks are exposed, wherein the insulative protection layer has at least a concave portion formed between two of the second conductive blocks; and removing the carrier.
