  • Publication number: 20180059550
    Abstract: In accordance with an embodiment of the disclosure, a tip array can include an elastomeric tip substrate layer comprising a first surface and an oppositely disposed second surface, the tip substrate layer being formed from an elastomeric material; a plurality of tips fixed to the first surface, the tips each comprising a tip end disposed opposite the first surface, the tips having a radius of curvature of less than about 1 micron; and an array of heaters disposed on the second surface of the tip substrate layer and configured such that when the tip substrate layer is heated by a heater, a tip disposed in a location of a heated portion of tip substrate layer is lowered relative to a tip disposed in a location of an unheated portion of the tip substrate layer.

  • Patent number: 9766551
    Abstract: In accordance with an embodiment of the disclosure, a method of patterning can include dividing an image into a set of frame sections; determining a tip pattern for a respective portion of an image to be patterned by each tip of the tip array in each frame section of the set of frame sections; disposing the tip array in a patterning position in a first location of the substrate corresponding to a location of the substrate in which the first frame section in the set of frame sections is to be patterned; projecting a first pattern of radiation onto the tip array to selectively irradiate one or more tips of the tip array and pattern the substrate, wherein the first pattern of radiation corresponds to a tip pattern for the first frame section; disposing the tip array in a patterning position in a second location of the substrate corresponding to a location of the substrate in which the second frame section in the set of frame sections is to be patterned; projecting a second pattern of radiation onto the tip array

  • Publication number: 20150210868
    Abstract: A method of forming a nanostructure on a substrate surface can include heating a substrate comprising a composition comprising a block copolymer and a nanostructure precursor to a temperature above the glass transition temperature of the block copolymer and below the decomposition temperature of the block copolymer to aggregate the nanostructure precursor to form a nanostructure precursor aggregated composition. The method can further include heating the nanostructure precursor aggregated composition to a temperature above the decomposition temperature of the nanostructure precursor to decompose the polymer and form the nanostructure.
