Abstract: A self-assembled nanostructure comprises first domains and second domains. The first domains comprise a first block of a block copolymer material and an activatable catalyst. The second domains comprise a second block and substantially without the activatable catalyst. The activatable catalyst is capable of generating catalyst upon application of activation energy, and the generated catalyst is capable of reacting with a metal oxide precursor to provide a metal oxide. A semiconductor structure comprises such self-assembled nanostructure on a substrate.

Abstract: A method of forming nanostructures may include forming a block copolymer composition within a trench in a material on a substrate, wherein the block copolymer composition may comprise a block copolymer material and an activatable catalyst having a higher affinity for a first block of the block copolymer material compared to a second block of the block copolymer material; self-assembling the block copolymer composition into first domains comprising the first block and the activatable catalyst, and second domains comprising the second block; generating catalyst from the activatable catalyst in at least one portion of the first domains to produce a structure comprising catalyst-containing domains and the second domains, the catalyst-containing domains comprising the first block and the catalyst; and reacting a metal oxide precursor with the catalyst in the catalyst-containing domains to produce a metal oxide-containing structure comprising the first block and metal oxide.
