Patent ID: 8062975

Claim:
A method for providing through substrate vias (TSVs), comprising: providing a substrate having an initial thickness between an initial back side and a front side thereof; forming an electronic device region in or on the substrate proximate the front-side and of a first depth; etching one or more front-side cavities of a first width and a second depth, and having substantially vertical first sidewalls; filling the front-side cavities with a first conductor so that the first conductor is in direct contact with the first sidewalls; removing material from the initial back side of the substrate to form a modified substrate having a modified thickness less than the initial thickness and expose a new back side thereof; etching one or more back-side cavities of a second width and a third depth, and having substantially vertical second sidewalls, thereby exposing one or more of the conductors in one or more of the front-side cavities; forming dielectric portions on the second sidewalls; and depositing a second conductor in the one or more back-side cavities electrically coupled to one or more of the first conductors of the front-side cavities.
