Patent number: 8334217Abstract: Embodiments of the invention relate to a method of functional materials deposition using a polymer template fabricated on a substrate. Such template forms an exposed and masked areas of the substrate material, and can be fabricated using polymer resists or Self-assembled monolayers. Deposition is performed using an applicator, which is fabricated in the shape of cylinder or cone made of soft elastomeric materials or laminated with soft elastomeric film. Functional materials, for example, metals, semiconductors, sol-gels, colloids of particles are deposited on the surface of applicator using liquid immersion, soaking, contact with wetted surfaces, vapor deposition or other techniques. Then wetted applicator is contacted the surface of the polymer template and rolled over it's surface. During this dynamic contact functional material is transferred selectively to the areas of the template. Patterning of functional material is achieved by lift-off of polymeric template after deposition.Type: GrantFiled: June 8, 2009Date of Patent: December 18, 2012Assignee: Rolith Inc.Inventor: Boris Kobrin

Patent number: 8318386Abstract: Embodiments of the invention relate to methods useful in the fabrication of nanostructured devices for optics, energy generation, displays, consumer electronics, life sciences and medicine, construction and decoration. Instead of nanostructuring using colloids of particles, special vacuum deposition methods, laser interference systems (holography), and other low-throughput limited surface area techniques, we suggest to use nanotemplate created by novel nanolithography method, “Rolling mask” lithography. This method allows fast and inexpensive fabrication of nanostructures on large areas of substrate materials in conveyor-type continuous process. Such nanotemplate is then used for selective deposition of functional materials. One of embodiments explains deposition of functional materials in the exposed and developed areas of the substrate. Another embodiment uses selective deposition of the functional material on top of such template.Type: GrantFiled: August 6, 2009Date of Patent: November 27, 2012Assignee: Rolith Inc.Inventor: Boris Kobrin
