Publication number: 20140037920Abstract: A hard-to-dry-etch material may be patterned by forming a layer of dry-etchable material on a surface of the hard-to-dry etch substrate, and dry etching the dry-etchable material. The hard-to-dry etch substrate produces substantial quantities of non-volatile etch byproducts that redeposit when subject to the dry etching. The dry-etchable material has similar material properties to the hard-to-dry-etch substrate material is formed. The dry-etchable material is one that does not produce substantial quantities of non-volatile etch byproducts that redeposit when the dry-etchable material is subject to the dry etching. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: ApplicationFiled: August 1, 2012Publication date: February 6, 2014Applicant: Rolith, Inc.Inventor: Boris Kobrin

Patent number: 8584703Abstract: This invention provides composite plastic articles and methods of making them. The articles can be fluidic or microfluidic devices having fluidic conduits and, optionally, pneumatic conduits that regulate flow in the fluidic conduits. The articles comprise a first substrate coated with a layer of a material that comprises, or onto which have been introduced, reactive groups. For example, the substrate can be a plastic coated with an oxide or a siloxane onto which hydroxyl groups have been introduced. These articles are covalently bonded with other articles comprising reactive groups on their surfaces, for example, polysiloxanes treated to have silanol groups. Certain articles have specified locations on their surfaces that are not bonded to the other piece. For example, the coating can be removed from these locations before bonding. Such locations can be useful as functional elements of various devices, such as valve seats in valves of microfluidic devices.Type: GrantFiled: November 18, 2010Date of Patent: November 19, 2013Assignee: IntegenX Inc.Inventors: Boris Kobrin, Iuliu I.

Patent number: 8545972Abstract: An improved vapor-phase deposition method and apparatus for the application of multilayered films/coatings on substrates is described. The method is used to deposit multilayered coatings where the thickness of an oxide-based layer in direct contact with a substrate is controlled as a function of the chemical composition of the substrate, whereby a subsequently deposited layer bonds better to the oxide-based layer. The improved method is used to deposit multilayered coatings where an oxide-based layer is deposited directly over a substrate and an organic-based layer is directly deposited over the oxide-based layer. Typically, a series of alternating layers of oxide-based layer and organic-based layer are applied.Type: GrantFiled: July 29, 2010Date of Patent: October 1, 2013Assignee: Applied Microstructures, Inc.Inventors: Boris Kobrin, Jeffrey D.

Publication number: 20130224636Abstract: Methods for fabricating nanopatterned cylindrical photomasks are disclosed. A master pattern having nanometer scale features may be formed on a master substrate. A layer of an elastomer material may be formed on a surface of a transparent cylinder. The master pattern may be transferred from the master to the layer of elastomer material on the surface of the transparent cylinder. Alternatively, a nanopatterned cylindrical photomask may be fabricated by forming a pattern having nanometer scale features on an elastomer substrate and laminating the patterned elastomer substrate to a surface of a cylinder. In another method, a layer of elastomer material may be formed on a surface of a transparent cylinder and a pattern having nanometer scale features may be formed on the elastomer material by a direct patterning process.Type: ApplicationFiled: February 14, 2013Publication date: August 29, 2013Applicant: Rolith, Inc.Inventor: Boris Kobrin

Patent number: 8425789Abstract: In anisotropic etching of the substrates, ultra-thin and conformable layers of materials can be used to passivate sidewalls of the etched features. Such a sidewall passivation layer may be a Self-assembled monolayer (SAM) material deposited in-situ etching process from a vapor phase. Alternatively, the sidewall passivation layer may be an inorganic-based material deposited using Atomic Layer Deposition (ALD) method. SAM or ALD s layer deposition can be carried out in a pulsing regime alternating with sputtering and/or etching processes using process gasses with or without plasma. Alternatively, SAM deposition is carried out continuously, while etch or sputtering turns on in a pulsing regime. Alternatively, SAM deposition and etch or sputtering may be carried out continuously.Type: GrantFiled: October 1, 2009Date of Patent: April 23, 2013Assignee: Rolith, Inc.Inventor: Boris Kobrin

Patent number: 8388908Abstract: This invention provides fluidic devices, in particular microfluidic devices, with diaphragm valves having low failure rates. Low failure rates are achieved by inhibiting sticking of the diaphragm to functional surfaces such as valve seats, valve chamber and fluidic channels and conduits. One way to implement this is to provide exposed surfaces facing the diaphragm, particularly valve seats, with a low energy material, such as a noble metal, a perfluorinated polymer, a self-assembled monolayer, hard diamond, diamond-like carbon or a metal oxide. In other embodiments, the valves are provided with ridges and the diaphragm is adhered to the fluidic or actuation layer with an adhesive material.Type: GrantFiled: May 27, 2010Date of Patent: March 5, 2013Assignee: IntegenX Inc.Inventors: Iuliu I.

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
