Patent number: 9139924Abstract: For forming a nickel mold, a metal and a corresponding etchant are selected such that the etchant selectively etches the metal over nickel. The metal is sputtered onto a surface of a template having nano-structures to form a sacrificial layer covering the nano-structures. Nickel is electroplated onto the sacrificial layer to form a nickel mold, but leaving a portion of the sacrificial layer exposed. The sacrificial layer is contacted with the etchant through the exposed portion of the sacrificial layer to etch away the sacrificial layer until the nickel mold is separated from the template. Subsequently, the nickel mold may be replicated or scaled-up to produce a replicate mold by electroplating, where the replicate mold has nano-structures that match the nano-structures on the template. The metal may be copper.Type: GrantFiled: August 23, 2012Date of Patent: September 22, 2015Assignee: Agency for Science, Technology and ResearchInventors: Kambiz Ansari, Christina Yuan Ling Tan, Yee Chong Loke, Jarrett Dumond, Isabel Rodriguez

Patent number: 8773015Abstract: Disclosed is a method for manufacturing an organic electroluminescent (EL) element which is provided with a pair of electrodes and two or more organic layers disposed between the electrodes, and which includes light-emitting layers as the two or more organic layers. The manufacturing method for an organic EL element includes: a step for forming one electrode of the pair of electrodes; a step for forming the two or more organic layers which have a periodic structure wherein the propagation direction of light propagating in a direction substantially perpendicular to the thickness direction of the light-emitting layers is inclined in said thickness direction; and a step for forming the other electrode of the pair of electrodes.Type: GrantFiled: November 9, 2010Date of Patent: July 8, 2014Assignees: Sumitomo Chemical Company, Limited, Agency for Science, Technology and ResearchInventors: Kyoko Yamamoto, Jarrett Dumond, Hong Yee Low

Patent number: 7704432Abstract: An imprint lithographic method for making a polymeric structure comprising the steps of: (a) providing a mold having a shape forming a mold pattern; (b) providing a substrate having a higher surface energy relative to said mold; (c) providing a polymer film on said mold, said polymer film having a selected thickness, wherein the selected thickness of the polymer film on the mold pattern is capable of forming at least one frangible region in the polymer film having a thickness that is less than the remainder of the polymer film; (d) pressing the mold and the substrate relatively toward each other to form said frangible region; and (e) releasing at least one of said mold and said substrate from the other, wherein after said releasing, said frangible region remains substantially attached to said mold while the remainder of said polymer film forms the polymeric structure attached to said substrate.Type: GrantFiled: May 18, 2006Date of Patent: April 27, 2010Assignee: Agency for Science, Technology and ResearchInventors: Jarrett Dumond, Hong Yee Low

Patent number: 7615179Abstract: The present invention is directed to micro- and nano-scale imprinting methods and the use of such methods to fabricate supported and/or free-standing 3-D micro- and/or nano-structures of polymeric, ceramic, and/or metallic materials, particularly for pixel segregation in OLED-based displays. In some embodiments, a duo-mold approach is employed in the fabrication of these structures. In such methods, surface treatments are employed to impart differential surface energies to different molds and/or different parts of the mold(s). Such surface treatments permit the formation of three-dimensional (3-D) structures through imprinting and the transfer of such structures to a substrate. In some or other embodiments, such surface treatments and variation in glass transition temperature of the polymers used can facilitate separation of the 3-D structures from the molds to form free-standing micro- and/or nano-structures individually and/or in a film.Type: GrantFiled: March 24, 2005Date of Patent: November 10, 2009Assignee: Agency For Science, Technology and ResearchInventors: Jarrett Dumond, Hong Yee Low
