  • Patent number: 8187797
    Abstract: A template having a first recess pattern is brought into contact with a mask material formed on a substrate. The mask material with which the first recess pattern is filled is cured. A mask material pattern is formed on the substrate by releasing the template from the mask material. A resist pattern is formed to cover a part of the mask material pattern by forming a resist on the mask material pattern and selectively irradiating radiation onto the resist and thereafter developing the resist. The substrate is processed by using the mask material pattern and the resist pattern as a mask.

  • Patent number: 8187516
    Abstract: A method of producing a bent rod includes impregnating fibers (1) with resin (2), introducing the impregnated fibers into a flexible plastic tube (3), bringing the flexible plastic tube to a desired bent form and crosslinking the resin with the fibers to produce the rod with the desired bent shape. The flexible plastic tube is formed from a material that has a very low friction coefficient and the flexible plastic tube remains in its position after the crosslinking to permit sliding movement of the bent rod relative to an adjacent structure.

  • Patent number: 8178032
    Abstract: The present invention generally relates to a mold assembly (32, 34) and a method of using the mold for the manufacture of composite parts which, more particularly, are generated from a strengthener in a generally solid phase and a matrix in a generally liquid phase. Various types of molds and processes may be used in order to impregnate a strengthener with a matrix such that a composite part may be manufactured, but the efficiency rate and the duration of the manufacturing process significantly varies depending on the chosen type of mold and process. The present invention relates to a mold assembly and to the manufacture of composites by using the mold assembly which includes the injection of the matrix in the mold assembly containing the strengthener and a deformable member (36) which favors the impregnation of the matrix toward the strengthener.

  • Patent number: 8178011
    Abstract: The present disclosure relates to techniques for replicating large-scale nano-pattern structures using a block copolymer structure as a mask in a replication process. Example methods may include performing self-assembling block copolymer reactions to create large self-assembling nano-structures. The nano-structures may then be replicated by using the large self-assembling nano-structure as a mask in nano-imprint lithography.

  • Patent number: 8178026
    Abstract: A nanoimprinting method includes: forming at a region for performing a first nanoimprinting process on a substrate, a first patterning region with a first affinity to resin; forming at a region for performing a second nanoimprinting process on the substrate, a second patterning region with a second affinity to resin, the second affinity being lower than the first affinity; applying the resin to the first patterning region and transferring a pattern of a mold to the resin by the first nanoimprinting process; and modifying the second patterning region to a region with affinity to resin that is higher than the second affinity, then applying the resin to the modified region, and performing the second nanoimprinting process to process the second patterning region thereby connecting patterns formed at the first patterning region and the second patterning region to each other.

  • Patent number: 8168107
    Abstract: 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.

  • Patent number: 8145457
    Abstract: Hot embossing may be more advantageous than other polymer microfabrication processes. An example embodiment of the present invention relates to a method and corresponding apparatus for developing a computationally inexpensive viscoelastic model for the hot embossing of complex patterns. These developed models may help engineers refine their selection of processing parameters based upon successive simulations of the embossing process. The example embodiment models deformation of a deformable body embossed with a stamp as a function of convolving a point-load-time response and a contact pressure distribution. In order to generate the point-load-time response, a time-dependent response of a surface of the thermoplastic to system inputs applied to an elemental region of the surface of the thermoplastic may be employed. The example embodiment generates an estimate of the contact pressure distribution as a function of the point-load-time response and an average pressure applied to the stamp.
