Paper Abstract
Directed self-assembly lithography (DSAL), which combines self-assembling materials and a lithographically
defined prepattern, is a potential candidate to extend optical lithography beyond 22 nm. To take full
advantage of DSAL requires diminishing not only systematic error modes but also random error modes by
carefully designing a lithographically defined prepattern and precisely adjusting process conditions. To
accomplish this with satisfactory accuracy, we have proposed a novel method to evaluate DSAL error modes
based on simulations using dissipative particle dynamics (DPD). We have found that we can estimate not only
systematic errors but also random errors qualitatively by simulations.
