Patent ID: 7605066

Claim:
A method for realizing an electric connection in a semiconductor electronic device between a nanometric circuit architecture and standard electronic components, the method comprising the steps of: a) providing, above a semiconductor substrate, a seed layer having at least a notched wall substantially perpendicular to said substrate, said wall defining n vertical recesses having a height equal to a thickness of said seed layer, said recesses being placed at a distance b 0 from one another and having depth a n and width b n ; b) realizing, by Multi-Spacer Patterning Technology (S n PT), n conductive nanowires of thickness t si alternated with insulating nanowires of thickness (t sp -t si ) wherein t sp is a width of a pair of the conductive and insulating nanowires, so as to obtain, at each realization of one of the conductive nanowires of a given order n, a filling or a completion of the filling of a corresponding one of the recesses of the same order by a respective elbow-like portion of said conductive nanowire, and the partial filling together with the conductive and insulating nanowires of lower order already realized, of the recesses of greater order by means of respective notched profile portions, thereby forming said nanometric circuit architecture; c) realizing, above said nanometric circuit architecture, an insulating layer; d) opening, in said insulating layer, n windows, each window being open substantially in correspondence with a respective one of the recesses, with exposure of at least part of the elbow-like portion of a respective one of the conductive nanowires present in said recess; and e) realizing, above said insulating layer, n conductive dies addressed towards said standard electronic components, the conductive dies respectively overlapping in correspondence with the respective windows to respective exposed parts of the respective elbow-like portions of the respective conductive nanowires with obtainment of n contacts realizing said electric connection.
