Figure 3. SEM images of lithographic and nanomesh patterns in circular and Y-junction templates.

Figure 3

(ac) Circular template. (a) The HSQ EBL template. (b) The SD45 BCP cylinders are templated by the PDMS-functionalized HSQ circles to form concentric rings. (c) Circular nanomesh pattern from SD16 over SD45. (df) Y-junction template. (d) The sacrificial PMMA EBL template. (e) The SD45 BCP cylinders are templated by the PMMA pattern to form three-direction arrays of cylinders with a central intersection. The PMMA template was removed during the etching process. (f) A Y-junction nanomesh pattern from SD16 over SD45. Scale bars, 500 nm.
