Abstract:
1. A method comprising: depositing a block copolymer structure on a substrate, said block copolymer structure having a plurality of blocks of a first polymer and a plurality of blocks of a second polymer, said blocks of said first polymer and said second polymer being chemically different and arranged such that blocks of the first polymer are adjacent to each other and blocks of the second polymer are adjacent to each other, and said block copolymer structure also having a first component deposited between adjacent blocks of said first polymer and a second component deposited between adjacent blocks of said second polymer; developing a template by removing either said first and second polymers or said first and second components from said block copolymer structure; and lithographically patterning a device utilizing said template.
