Patent ID: 8299454

Claim:
A microelectronic device comprising: a substrate; a coupling layer on the substrate, wherein the coupling layer comprises a different material than the substrate; a linking layer on a surface of the coupling layer opposite the substrate, wherein the linking layer comprises a different material than the coupling layer and defines a nano line arrangement region having a length greater than a width thereof; a mask pattern on the coupling layer, the mask pattern having a trench extending therethrough to expose the linking layer, wherein opposing sidewalls of the trench in the mask pattern and the exposed linking layer therebetween define a nano line arrangement groove, and wherein sidewalls of the nano line arrangement groove include the opposing sidewalls of the mask pattern; and at least one nano line on the linking layer in the nano line arrangement region, wherein the at least one nano line has a length greater than the width of the nano line arrangement region and is coupled to the surface of the coupling layer by the linking layer, wherein the surface of the coupling layer having the linking layer thereon defines a recess that extends toward the substrate relative to a portion of the coupling layer having the mask pattern thereon, and wherein the sidewalls of the nano line arrangement groove further include opposing sidewalls of the coupling layer exposed by the recess in the coupling layer.
