THROUGH SUBSTRATE VIA STRUCTURE AND METHOD FOR FABRICATING THE SAME

摘要

A through substrate via (TSV) structure is provided, including: a substrate; an opening formed in a portion of the semiconductor substrate; a dielectric layer formed on the sidewall of the opening; a conductive pillar formed inside the opening; and at least a portion of the dielectric layer is removed to form void. Also provided is a method for fabricating a through substrate via (TSV) structure.
