The increasing cost and complexity of processes needed to keep up with the ever increasing demand for more powerful processors in the IC industry, lead to smaller and smaller feature sizes. Photolithography, once the workhorse for nanostructuration, reaches now its physical limits in terms of resolution. Other, alternative methods have thus to be found in order to continue producing more efficient integrated circuits, while keeping the production costs at a reasonable level. The combination of conventional photolithography and directed self-assembly of block copolymers (BCP) seems to be one promising alternative. Block copolymers have the unique property to phase separate at the nanometer scale driven by the chemical incompatibility (descri...
