Abstract:
1. A method of forming a pattern, comprising: forming a main body of copolymer across a substantially planar upper surface of a substrate; inducing self-assembly of the copolymer within the main body to form a plurality of cylinders across the substrate; and while inducing the assembly of the cylinders from the copolymer, obtaining a pattern of the cylinders across the main body of the copolymer through fluid communication of the main body of copolymer with at least one reservoir of copolymer in a trench; the substantially planar upper surface of the substrate being outside of the trench; the trench extending primarily along a first horizontal direction, and having a sidewall; the cylinders extending primarily along a second horizontal direction which is substantially orthogonal to the first horizontal direction; the cylinders extending from the main body to across the sidewall and over the trench.
