Figure S1 Lamellar morphologies of (a) a thermally annealed film and (b) - (d) films solvent annealed with various P2VP-selective vapors. The number indicates the swelling ratio (SR) of each BCP film.

Figure S2 Cylindrical morphologies obtained by treating BCP films with various P2VP selective solvents.

Figure S3 An image of multilayer spheres. This is evidence that the monolayer dots in Fig. 3g and 3h are not from perpendicular cylinders.
Figure S4 The swelling ratios of P2VP and PDMS homopolymers treated with different solvent vapors. The vapors were produced at the same conditions. (Surface-to-empty-volume ratio of the solvent annealing system = 0.579). The details of solvent annealing can be found elsewhere.3 5
Figure S5 Line edge roughness (LER) estimated from various line patterns. The image analysis was performed in the SEM images with an area of 200 nm х 200 nm.
