Abstract
A method for realizing a nanometric circuit architecture includes: realizing plural active areas on a semiconductor substrate; realizing on the substrate a seed layer of a first material; realizing a mask-spacer of a second material on the seed layer in a region comprised between the active areas; realizing a mask overlapping the mask-spacer and extending in a substantially perpendicular direction thereto; selectively removing the seed layer exposed on the substrate; selectively removing the mask and the mask-spacer obtaining a seed-spacer comprising a linear portion extending in that region and a portion substantially orthogonal thereto; realizing by MSPT from the seed-spacer an insulating spacer reproducing at least part of the profile of the seed-spacer; realizing by MSPT a nano-wire of conductive material from the seed-spacer or insulating spacer, the nano-wire comprising a first portion at least partially extending in the region and a second portion contacting a respective active area.
