  • Method for making patterns on the surface of a substrate using block copolymers
    Patent number: 9566610
    Abstract: A method for making patterns on the surface of a substrate by graphoepitaxy, includes depositing a layer of resin on the surface of the substrate; making patterns in the resin on the surface of a substrate; curing the patterns in the resin by producing a layer of amorphous carbon on the surface of the patterns in the resin; depositing a layer of statistical copolymer after curing the patterns in the resin; grafting the layer of statistical copolymer onto the patterns in the resin by annealing; and depositing a layer of a block copolymer into the spaces defined by the patterns in the resin after curing the patterns and the grafting of the layer of statistical copolymer.
    Type: Grant
