Abstract

The invention provides compositions and methods for inducing and enhancing order and nanostructures in organosilicon block copolymers compositions by including certain organic additives in such compositions that include one or more moieties comprising a hydrogen bond acceptor or a hydrogen bond donor. Such block copolymer compositions may be used, for example, as a mask for lithographic patterning as is used, for example, during various stages of semiconductor device fabrication.
