Abstract: A method of forming a patterned chemical epitaxy template, for orientation of a self-assemblable block copolymer comprising first and second polymer blocks, on a surface of a substrate, the method including applying a primer layer of a primer composition to the surface, the primer composition comprising a first polymer moiety having a chemical affinity with the first polymer blocks and a second polymer moiety having a chemical affinity with the second polymer blocks, selectively exposing the surface, the primer layer and any overlying layer to actinic radiation to provide exposed and unexposed regions, to render labile the first polymer moiety in the exposed region, and removing the labile first polymer moiety from the exposed region to deplete the primer layer surface in the exposed region of first polymer moiety to form the patterned chemical epitaxy template.

Abstract: A BCP having first block of first monomer and second block of second monomer, adapted to undergo a transition from disordered state to ordered state at a temperature less than T0D, further including a bridging moiety having a functional group to provide hydrogen bonding between bridging moieties of adjacent first and second BCP molecules when in the ordered state and at a temperature in excess of a glass transition temperature Tg for the BCP. Composition including BCP comprising first block of first monomer and second block of second monomer, and a crosslinking compound having first and second terminal groups joined by a central moiety and arranged to crosslink second blocks of adjacent first and second BCP molecules by providing non-covalent bonding between the terminal groups and a functional group of the second monomer of the second blocks when the BCP is in the ordered state.

Abstract: A method of forming a self-assembled block polymer layer, oriented to form an ordered array of alternating domains, is disclosed. The method involves providing a layer of the self-assemblable block copolymer on the substrate and depositing a first surfactant onto the external surface of the layer prior to inducing self-assembly of the layer to form the ordered array of domains. The first surfactant has a hydrophobic tail and a hydrophilic head group and acts to reduce the interfacial energy at the external surface of the block copolymer layer in order to promote formation of assembly of the block copolymer polymer into an ordered array having the alternating domains.

Abstract: A block copolymer, adapted to self-assemble to form an ordered pattern on a substrate, has first and second blocks with a terminal moiety covalently bonded to the end of the first block. The molecular weight of the terminal moiety is 20% or less than that of the block copolymer and the terminal moiety has a low chemical affinity for the first block. The terminal moiety can assist the accurate positional placement of the domains of the ordered array and lead to improved critical dimension uniformity and/or reduced line edge roughness. The polymer may be useful in combination with a graphoepitaxy template, where the terminal moiety is chosen to associate with a sidewall of the template. This may reduce undesired aggregation of polymer domains at a sidewall and/or assist in domain placement accuracy.
