Patent number: 8168107Abstract: Example embodiments relate to a method of forming a three-dimensional micro pattern or a multi-step pattern using a nano imprinting process and a method of manufacturing a mold to form such a pattern. A molding polymer may be patterned in a one-step shape on a substrate having UV barrier patterns, thereby easing the manufacture of a mold for multi-step imprinting and simplifying the formation of a multi-step pattern using the one-step shaped mold by avoiding the repetition of more complicated processes. Consequently, it may be possible to form a relatively large-area micro pattern, a relatively large-area pattern usable in flat panel displays, and a nano pattern having a size of several tens of nanometers in a semiconductor process, thereby contributing to the reduction of process costs, the reduction of process time, and the improvement of production yield.Type: GrantFiled: May 28, 2009Date of Patent: May 1, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Young Tae Cho, Young Suk Sim, Jeong Gil Kim

Then, the transmissive stamper is irradiated with ultraviolet rays to cure the intermediate layer. Thereafter, the supporting base is removed from the protection layer. These steps produce a multilayered optical recording medium.Type: GrantFiled: December 14, 2009Date of Patent: November 30, 2010Assignee: Canon Kabushiki KaishaInventor: Tomoyuki Hiroki

Publication number: 20100258966Abstract: A reticle comprising isolated pillars is configured for use in imprint lithography. In some embodiments, on a first substrate a pattern of pillars pitch-multiplied in two dimensions is formed in an imprint reticle. The imprint reticle is brought in contact with a transfer layer overlying a series of mask layers, which in turn overlie a second substrate. The pattern in the reticle is transferred to the transfer layer, forming an imprinted pattern. The imprinted pattern is transferred to the second substrate to form densely-spaced holes in the substrate. In other embodiments, a reticle is patterned by e-beam lithography and spacer formations. The resultant pattern of closely-spaced pillars is used to form containers in an active integrated circuit substrate.Type: ApplicationFiled: June 24, 2010Publication date: October 14, 2010Applicant: MICRON TECHNOLOGY, INC.Inventor: Gurtej S.

Patent number: 7803308Abstract: The present invention provides a method for separating a mold from solidified imprinting material that includes creating deformation in the template in which the mold is included. The deformation is sufficient to create a returning force that is greater than an adhesion forced between the solidified imprinting material and the mold. For example, the deformation may result from a pressure differential created between the mold and a side of the template disposed opposite to the mold. In this manner, the distortion may be undulations in the template of sufficient magnitude to contact a substrate upon which the solidified imprinting material is disposed.Type: GrantFiled: December 1, 2005Date of Patent: September 28, 2010Assignee: Molecular Imprints, Inc.Inventors: Mahadevan GanapathiSubramanian, Byung-Jin Choi, Michael N.

Publication number: 20100239889Abstract: The present invention provides a technique capable of manufacturing a resin stamper at a low cost. A method of manufacturing a plate-shaped resin stamper includes: pressing a resin composite base material against a mother stamper having a pattern formed on the surface thereof by compression molding to transfer the pattern of the mother stamper to the composite base material; and punching the composite base material. In the manufacturing method, the resin composite base material includes at least one curing resin. In addition, during the compression molding, a portion of the composite base material is cured by active energy beams or heat, the pattern is transferred to the composite base material, and the composite base material is punched, thereby manufacturing the resin stamper.Type: ApplicationFiled: October 16, 2008Publication date: September 23, 2010Applicant: Showa Denko K.K.Inventors: Hiroshi Uchida, Masato Fukushima, Yuko Sakata

Publication number: 20100230853Abstract: Disclosed is a method for printing a surface of a non-planar injection-molded object, wherein a thin plastic sheet is provided and printed with a desired pattern. A mold corresponding to a desired final product of injection molding is provided to press the plastic sheet so as to form a plastic shell that has a shape corresponding to the final product and can compliantly positioned in an injection mold. The plastic shell is positioned in an injection mold to combine with a plastic injection molding made with the injection mold. The pattern printed on the plastic sheet is shown on an inside surface of the final product through the plastic shell that is formed by hot pressing the plastic sheet and tightly combined with the final product so as to directly molded with the final product and is not susceptible to color fading or detachment due to abrasion, impact or washing.Type: ApplicationFiled: March 10, 2009Publication date: September 16, 2010Inventor: Yen-Pin Su
