Patent ID: 7891090

Claim:
A method for manufacturing an interposer including a body and a plurality of probes connected to said body, the method comprising: a step of manufacturing said body including the sub-steps of: preparing a first substrate having one surface side and the other surface side and being capable of being processed by dry etching; forming a plurality of through holes in said first substrate by dry etching; and making said through holes into conductive holes through a bottom-up fill process, the conductive holes capable of conducting electricity, and wherein the bottom-up fill process includes depositing a conductive layer from a bottom portion to a top portion of the through hole; a step of manufacturing said plurality of probes including the sub-steps of: preparing a second substrate; forming a desired shaped mold on a surface of said second substrate using a resist; and forming a plurality of first probes in the desired shape with said mold; and a step of connecting the ends of said plurality of conductive holes on one surface side of said first substrate and said plurality of first probes on said second substrate.
