  • Publication number: 20110232515
    Abstract: A method of patterning a substrate is disclosed. An ink material is chemisorbed to at least one region of a stamp and the chemisorbed ink material is transferred to a receptor substrate. The ink material has greater chemical affinity for the receptor substrate than for the at least one region of the stamp. A method of forming the stamp is also disclosed, as are the stamp and a patterning system.

  • Patent number: 7910660
    Abstract: Zwitterionic block copolymers having oppositely charged or chargeable terminal groups, and methods of making and using the same, are disclosed. The zwitterionic block copolymers can undergo microphase separation. In some embodiments a zwitterionic block copolymer includes a first terminal block having a positively charged or chargeable group at a terminal end, and a second terminal block having a negatively charged or chargeable group at another terminal end. The zwitterionic block copolymer is configured to undergo microphase separation to assemble into alternating lamellar domains; with one of the alternating domains being composed of the first terminal block, and with another of the alternating domains being composed of the second terminal block.

  • Publication number: 20100102415
    Abstract: Methods of forming metal oxide structure and methods of forming metal oxide patterns on a substrate using a block copolymer system formulated for self-assembly are disclosed. The metal oxide structures and patterns may be used, for example, as a mask for sublithographic patterning during various stages of semiconductor device fabrication. A block copolymer at least within a trench in the substrate and including at least one soluble block and at least one insoluble block may be annealed to form a self-assembled pattern including a plurality of repeating units of the soluble block laterally aligned with the trench and positioned within a matrix of the insoluble block. The self-assembled pattern may be exposed to a metal oxide precursor which impregnates the soluble block. The metal oxide precursor may be oxidized to form a metal oxide. The self-assembled pattern may be removed to form a pattern of metal oxide lines on the substrate surface.
