TL;DR: In this article, a bit-patterned media (BPM) fabrication method was proposed for magnetic data recording at > 1 Tb/in 2 and circumvents many of the challenges associated with extending conventional granular media technology.

TL;DR: Infrared photoinduced force microscopy has demonstrated the ability to spatially map nm-scale patterns of the individual chemical components of two different types of self-assembled block copolymer films, and provides a powerful new analytical method for deepening the understanding of nanomaterials.

TL;DR: In this paper, a method for making an imprint mold uses sidewall spacer line doubling, but without the need to transfer the sidewal spacer patterns into the mold substrate, and the resulting mold is a substrate with pillars of sidewall spacers patterned as stripes and extending from the substrate.

TL;DR: Directed self-assembly of block copolymers (BCPs) on chemically nanopatterned surfaces (or chemical patterns) combines advantages of conventional photolithography and polymeric materials and shows promise for meeting a sufficiently inclusive set of manufacturing constraints for applications in semiconductors and data storage.

TL;DR: In this paper, a method for making a chemical contrast pattern using directed self-assembly of block copolymers and sequential infiltration synthesis (SIS) of an inorganic material is presented.
