FIG. 1.

(Color online) Relationship between film thickness of the copolymer and the pull-up velocity in the dip-coating process onto Si substrate.

FIG. 2.

(a) Scanning electron microscope (SEM) image of the DLC slope on the Si substrate. Angle of the slope is 60°. [(b) and (c)] SEM images of the PS-b-PMMA patterns formed on the DLC slope pretreated with PS-r-PMMA. Sparse patterns were not found.

FIG. 3.

(Color online) Relationship between film thickness of the copolymer and the pull-up velocity in the dip-coating process onto Au substrate.

Image of FIG. 4.
FIG. 4.

(a) SEM images of the DLC slope pretreated with Au. Angle of the slope is 60°. SEM images of the PS-b-PMMA patterns; [(b) and (c)] on the slope, (d) on the boundary between the slope and a flat surface, and (e) on a flat surface. Dense nanoscale patterns are formed.

Image of FIG. 5.
FIG. 5.

[(a), (c), and (e)] SEM images of the DLC slope pretreated with Au. [(b), (d), and (f)] SEM images of the PS-b-PMMA patterns on the slope. Dense nanoscale patterns are formed. Angles of the slope are [(a) and (b)] 70°, [(c) and (d)] 80°, and [(e) and (f)] 90°. Then, we evaluated the surface of the tip in case of 90°, whereas we evaluated the slopes in cases of 70° and 80°.
