Claim:
1. A method of forming a semiconductor structure comprising: forming a plurality of first conductive pillars on a first substrate, wherein forming the plurality of first conductive pillars comprises: forming a masking layer on a masked region of a first substrate, and wherein an unmasked region of the first substrate comprises a plurality of electrical connections; and forming a conductive material in the unmasked region, forming the plurality of first conductive pillars on the first substrate; forming a first set of conductive nanowires on a first surface of the plurality of first conductive pillars, wherein forming a first set of conductive nanowires comprises: following the formation of the first set of conductive nanowires, removing the masking layer and porous layer using laser ablation, wherein laser ablation selectively removes the masking layer and porous layer with respect to the first set of conductive nanowires; forming a plurality of second conductive pillars on a second substrate; forming a second set of conductive nanowires on a second surface of the plurality of second conductive pillars; and forming an electrical connection between the first pillar and the second pillar by joining the first set of conductive nanowires with the second set of conductive nanowires.
