A35. 00005: Hexagonal pattern coarsening in cylinder-forming PS-b-PMMA block copolymer thin films*AbstractPresenter:Gabriele Seguini(IMM-CNR)Authors:Gabriele Seguini(IMM-CNR)Michele Perego(IMM-CNR)The grain coarsening in thin films (~ 30 nm) of cylinder forming PS-b-PMMA BCP (N= 379-1281) was accomplished by tuning of the annealing temperature and time in a RTP machine. The order of the hexagonal pattern was quantified by measuring the correlation length.
