Abstract (en)

[origin: WO2016193581A1] The invention concerns a method for reducing the defectivity of a block copolymer film (BPC1), the bottom surface of which is in contact with a previously neutralised surface (N) of a substrate (S) and the top surface of which is covered by a top surface neutralisation layer (TC), so as to obtain an orientation of the nano-domains of said block copolymer (BPC1) perpendicular to the two bottom and top interfaces, said method being characterised in that said top surface neutralisation layer (TC) implemented in order to cover the top surface of the block copolymer film (BCP1) is constituted by a second block copolymer (BPC2).
