Patent number: 8221665Abstract: The invention concerns a process of manufacturing optical components. A replication tool, a sub-master or a replica is manufactured using a structured element (for example a master) and a substrate. A structure of the structured element is replicated into liquid or plastically deformable material disposed at a first place on said substrate, then hardened to make it dimensionally stable, whereon the structured element is removed. These replicating, hardening and removing steps are repeated for a second, third, etc. place on said substrate the same structured element.Type: GrantFiled: June 9, 2006Date of Patent: July 17, 2012Assignee: Heptagon OyInventors: Hartmut Rudmann, Andreas Maciossek, Markus Rossi

Patent number: 8216494Abstract: A method for making a mold, the method includes steps of: providing a substrate and a retaining member, the retaining member being made of polytetrafluoroethylene, and being ring-shaped; engaging the substrate with the retaining member; disposing viscous liquid polydimethyl siloxane containing material on the substrate within the retaining member; rotating the retaining member and the substrate to cause the polydimethyl siloxane containing material to spread out on the substrate and form a polydimethyl siloxane containing layer; press-molding the polydimethyl siloxane containing layer using a stamper to form one or more molding portions on the polydimethyl siloxane containing layer; solidifying the polydimethyl siloxane containing layer with the one or more molding portions; separating the stamper from the polydimethyl siloxane containing layer; and separating the substrate from the retaining member to obtain a mold.Type: GrantFiled: November 4, 2009Date of Patent: July 10, 2012Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Yung-Lun Huang

Publication number: 20120126449Abstract: Nanostructured assemblies are manufactured by condensing an evaporated wetting agent onto a nanostructure array formed from a plurality of generally aligned carbon nanotubes or other nanostructures. The condensed wetting agent draws the individual nanostructures together to form various geometries of nanostructured assemblies based on various parameters including process variables and the starting shape and dimensional features of the nanostructure array. Various simple and complex geometries can be achieved in this manner, including geometries that are curved, bent, or twisted. Adjacent nanostructure arrays of the same or different starting geometries can be shaped into compound or interrelating structures. Additional process steps such as plasma etching, coating and others can be used to control the shaping and structural attributes of the nanostructured assemblies. A method of making a molded replica of a shaped nanostructure array is also disclosed.Type: ApplicationFiled: March 31, 2010Publication date: May 24, 2012Applicant: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Anastasios John Hart, Sameh Tawfick, Michael DeVolder, Davor Copic

Publication number: 20120123135Abstract: A silsesquioxane resin is applied on top of the patterned photo-resist and cured to produce a cured silsesquioxane resin on top of the pattern surface. Subsequently, an aqueous base stripper or a reactive ion etch recipe containing CF4 is used to “etch back” the silicon resin to the top of the photoresist material, exposing the entire top surface of the photoresist. Then, a second reactive ion etch recipe containing O2 to etch away the photoresist. The result is a silicon resin film with via holes with the size and shape of the post that were patterned into the photoresist. Optionally, the new pattern can be transferred into the underlying layer(s).Type: ApplicationFiled: June 22, 2010Publication date: May 17, 2012Inventors: Michael L. Bradford, Eric Scott Moyer, Kasumi Takeuchi, Sheng Wang, Craig Rollin Yeakle

Patent number: 8178025Abstract: An embossing system is provided for embossing at least a portion of a web comprising a first roll and at least a second roll. The first roll and second roll may define a first nip for embossing the web. At least one of the first roll and the second roll has elongated embossing elements extending substantially in the machine direction and optionally at least one of the first and second rolls has elongated embossing elements extending substantially in the cross-machine direction. At least one of the first roll and the second roll may also have perforate embossing elements extending substantially in the cross-machine direction that may or may not be elongated. The embossing elements are capable of imparting one or both of a cube embossing pattern or a perforate emboss on the web. The web may be a cellulosic fibrous web, a portion of which is lignin-rich, high coarseness fiber having generally tubular fiber configuration. In addition, the web may be creped with an undulatory creping blade.Type: GrantFiled: December 3, 2004Date of Patent: May 15, 2012Assignee: Georgia-Pacific Consumer Products LPInventors: Anthony O.

Publication number: 20120114780Abstract: A photopolymer die for foil stamping, foil printing, embossing, debossing, or a combination thereof is disclosed. The die has a metal backing plate on which is mounted a photopolymer layer which has a number of micro-grooves therein. Preferably the micro-grooves are arranged in a swatch like pattern. Preferably images have adjacent regions each with a different pattern of micro-grooves. The spacing between adjacent micro-grooves can be resolvable by the human eye, or cannot.Type: ApplicationFiled: May 11, 2010Publication date: May 10, 2012Applicant: WATERMARX TECHNOLOGY PTY LIMITEDInventors: Alan John Fawcett, Angela Mary O'Dea
