Keywords: breath figure; nanopatterned template; polymer blend lithography (PBL); self-assembled monolayer (SAM); self assembly; spin coating; vapor phase; Introduction Self-assembled monolayers (SAMs) are well-known and have been intensively studied for many years

• formation of so-called breath figures, which are formed at high relative humidity (over 60%) due to water condensation on the evaporatively cooled polymer solution [60][61]. The breath figure technique can be applied to generate nearly hexagonal arrays of holes [61] or for the fabrication of 3-D structures

• [62]. Water droplets are introduced into the polymer solution film and leave behind holes after the film has solidified. These breath figure structures can be found both in films of one-polymer systems, such as PMMA in THF, and of polymer-blend systems. In this article we present a method to obtain a
