Claim:
1. A method, comprising: a) lithographically transferring an initial pattern of an initial template to a substrate; b) applying a layer of block copolymer to the substrate after the transferring of the initial pattern, and performing block copolymer self-assembly of the layer of block copolymer with a density multiplication factor k; c) creating a subsequent pattern by removing a block from the layer of block copolymer after self-assembly for a subsequent template with the density multiplication factor k; d) determining whether or not the subsequent pattern meets a design specification; and e) repeating steps a)-d) with the subsequent template as the initial template until the subsequent pattern meets the design specification.
