METHOD FOR THE PERPENDICULAR ORIENTATION OF NANODOMAINS OF BLOCK COPOLYMERS, USING STATISTICAL OR GRADIENT COPOLYMERS, THE MONOMERS OF WHICH DIFFER AT LEAST IN PART FROM THOSE PRESENT IN EACH OF THE BLOCKS OF THE BLOCK COPOLYMER

摘要

Wherein a random or gradient copolymer of monomers at least partially different from the monomers present in each block of the block copolymer is used. The present invention relates to a method for vertically orienting nano-domains of a block copolymer on a substrate using a lower layer of random or gradient copolymers of at least partially different monomers with those present in each block of the block copolymer.
