  • Composite tip array for polymer pen lithography
    Patent number: 9079338
    Abstract: A method of preparing a tip for lithography, includes forming a mold having at least one recess; disposing a first polymer in the recess to form an apex of the tip,; curing the first polymer in the recess; and disposing a second polymer in the recess to form a base of the tip. The Young's Modulus of the second polymer is lower than the Young's Modulus of the first polymer. The tip structure for lithography includes a substrate, and a layered structure including a tip having an apex of a first polymer and a base of a second polymer. The first polymer is less resiliently deformable than the second polymer.
