Formation of sub-7 nm feature size PS-b-P4VP block copolymer structures by solvent vapour process [PDF]

, 2015
The nanometer range structure produced by thin films of diblock copolymers makes them a great of interest as templates for the microelectronics industry. We investigated the effect of annealing solvents and/or mixture of the solvents in case of symmetric
