Abstract
Lithographically-induced self-assembly (LISA) is a newly discovered pattern formation phenomenon where a plate called mask, placed a distance above a thin polymer film heated above Tg, causes the polymer film to flatten on another plate and to assemble into periodic micro-pillar arrays. The observation of other patterns, such as concentric rings and parallel lines in LISA is described in polymethyl methacrylate films. It is found that the polymer viscosity plays a key role in determining the micropatterns formed in LISA. At a lower viscosity, periodic pillars are formed while at a higher viscosity, concentric rings are formed.
