Method for forming a chemical guiding structure on a substrate and chemoepitaxy method

A method for forming a chemical guiding structure intended for self-assembly of a block copolymer by chemoepitaxy, where the method includes forming on a substrate a functionalisation layer made of a first polymer material having a first chemical affinity with respect to the block copolymer; forming...

Beschreibung
Zusammenfassung:	A method for forming a chemical guiding structure intended for self-assembly of a block copolymer by chemoepitaxy, where the method includes forming on a substrate a functionalisation layer made of a first polymer material having a first chemical affinity with respect to the block copolymer; forming on the substrate guiding patterns made of a second polymer material having a second chemical affinity with respect to the block copolymer, different from the first chemical affinity, and wherein the guiding to patterns have a critical dimension of less than 12.5 nm and are formed by means of a mask comprising spacers.
