The miniaturization of integrated circuits is largely dependent on optical lithography which is used to define the minimum size that can be obtained on a circuit. Currently, considerable resources are being deployed to go beyond the resolution limit of the optical systems that are in production. Among the techniques that are envisaged, block copolymer self-assembly makes it possible to reduce the resolution of the optical systems used and thus appears as a possible solution. Block copolymers are polymer chains consisting of two polymers. Under the action of heat, a mixture of block copolymers will be organized so that the polymers form disjoint and regular domains. Then one of the two domains can be etched to form the desired patterns. By c...
