Modelling of correlation length evolution for a BCP from 150°C to the target temperature 180°C (top) and 230°C (bottom). The figures on the left [(a) and (c)] illustrate the influence of the initial correlation length. The annealing is performed first with a temperature ramp of 1°C s−1 and then isothermal annealing once the target temperature is reached, as indicated by the vertical line. For the figures on the right [(b) and (d)], the BCP film is annealed using different temperature ramp rates (from 0.1°C s−1 to 40°C s−1 and then kept at constant temperature for a few min). The initial correlation length is 90 nm. All ramps start at t = 0 s. The correlation length during the ramp is represented by solid lines and dashed lines when the isotherm is reached.
