Patent number: 9782917Abstract: Aspects of the present disclosure describe cylindrical molds that may be used to produce cylindrical masks for use in lithography. A structured porous layer may be deposited on an interior surface of a cylinder. A radiation-sensitive material may be deposited over the porous layer in order to fill pores formed in the layer. The radiation-sensitive material in the pores may be cured by exposing the cylinder with a light source. The uncured resist and porous layer may be removed, leaving behind posts on the cylinder's interior surface.

Publication number: 20120282554Abstract: Embodiments of the invention relate to methods and apparatus useful in the nanopatterning of large area substrates, where a rotatable mask is used to image a radiation-sensitive material. Typically the rotatable mask comprises a cylinder. The nanopatterning technique makes use of Near-Field photolithography, where the mask used to pattern the substrate is in contact or close proximity with the substrate. The Near-Field photolithography may make use of an elastomeric phase-shifting mask, or may employ surface plasmon technology, where a rotating cylinder surface comprises metal nano holes or nanoparticles.Type: ApplicationFiled: July 19, 2012Publication date: November 8, 2012Applicant: Rolith, Inc.Inventors: Boris Kobrin, Ian McMackin

Patent number: 7981481Abstract: The present invention provides a method of controlling the distribution of a fluid on a body that features compensating for varying distribution of constituent components of a composition that moved over a surface of a substrate. To that end, the method includes generating a sequence of patterns of liquid upon a substrate, each of which includes a plurality of spaced-apart liquid regions, with voids being defined between adjacent liquid regions. A second of the patterns of liquid of the sequence is arranged so that the liquid regions associated therewith are in superimposition with the voids of a first of the patterns of liquid of the sequence.Type: GrantFiled: December 8, 2006Date of Patent: July 19, 2011Assignee: Molecular Imprints, Inc.Inventors: Frank Xu, Ian McMackin, PanKaj B.

Publication number: 20070228608Abstract: A method/process for curing imprint on a template prior to contact with a substrate. A curing process is used to adhere the imprint to a wafer or substrate. Monomer is deposited on a template and then partially cured using a UV exposure. The exposure is controlled so that the imprint is cured past the gel point, but still retains a thin liquid layer of uncured monomer at the surface that will bond with the wafer. Further, this partially cured layer enables the alignment adjustments between the template and the substrate to be performed after contact between the two without pulling any monomer out of the features.Type: ApplicationFiled: March 30, 2007Publication date: October 4, 2007Applicant: MOLECULAR IMPRINTS, INC.Inventors: Steven Shackleton, Pankaj Lad, Ian McMackin, Frank Xu, Sidlgata Sreenivasan
