  • Patent number: 8802747
    Abstract: A lithography method for forming nanoparticles includes patterning sacrificial material on a multilayer substrate. In some cases, the pattern is transferred to or into a removable layer of the multilayer substrate, and functional material is disposed on the removable layer of the multilayer substrate and solidified. At least a portion of the functional material is then removed to expose protrusions of the removable layer, and pillars of the functional material are released from the removable layer to yield nanoparticles. In other cases, the multilayer substrate includes the functional material, and the pattern is transferred to or into a removable layer of the multilayer substrate. The sacrificial layer is removed, and pillars of the functional material are released from the removable layer to yield nanoparticles.
