20140091476 | DIRECTED SELF ASSEMBLY OF BLOCK COPOLYMERS TO FORM VIAS ALIGNED WITH INTERCONNECTS - A method of an aspect includes forming an interconnect line etch opening in a hardmask layer. The hardmask layer is over a dielectric layer that has an interconnect line disposed therein. The interconnect line etch opening is formed aligned over the interconnect line. A block copolymer is introduced into the interconnect line etch opening. The block copolymer is assembled to form a plurality of assembled structures that are spaced along a length of the interconnect line etch opening. An assembled structure is directly aligned over the interconnect line that is disposed within the dielectric layer. | 04-03-2014 |
