  • Patent number: 10059820
    Abstract: Hybrid pre-patterns were prepared for directed self-assembly of a given block copolymer capable of forming a lamellar domain pattern. The hybrid pre-patterns have top surfaces comprising independent elevated surfaces interspersed with adjacent recessed surfaces. The elevated surfaces are neutral wetting to the domains formed by self-assembly. Material below the elevated surfaces has greater etch-resistance than material below the recessed surfaces in a given etch process. Following other dimensional constraints of the hybrid pre-pattern described herein, a layer of the given block copolymer was formed on the hybrid pre-pattern. Self-assembly of the layer produced a lamellar domain pattern comprising self-aligned, unidirectional, perpendicularly oriented lamellae over the elevated surfaces, and parallel and/or perpendicularly oriented lamellae over recessed surfaces. The domain patterns displayed long range order along the major axis of the pre-pattern.

  • Patent number: 9977339
    Abstract: Techniques herein include systems and methods that provide a spatially-controlled projection of electromagnetic radiation, such as light, onto a substrate as a mechanism of controlling or modulating critical dimensions of various features and structures being micro-fabricated on a substrate. Combining such spatial light projection with photolithographic exposure can achieve significant improvements in critical dimension uniformity across a surface of a substrate. In general, methods herein include patterning processes that identify or receive a critical dimension signature that spatially characterizes critical dimension values that correspond to the substrate. A pattern of electromagnetic radiation is projected onto a patterning film coated on substrate using a digital pixel-based projection system. A conventional photolithographic exposure process is executed subsequent to, or prior to, the pixel-based projection.

  • Patent number: 9182673
    Abstract: Methods are disclosed for depositing a template for directed self-assembly of a self-assemblable block polymer on a surface of a substrate. The method involves providing a chemical epitaxy pattern of alternating first and second regions having differing chemical affinities for first and second blocks of the polymer on the surface by photolithography, and providing spaced graphoepitaxy features on the surface by photolithography. The chemical epitaxy pattern is aligned with and located between pairs of spaced graphoepitaxy features. The spaced graphoepitaxy features and chemical epitaxy pattern are arranged to act together to direct self-assembly of the self-assemblable block copolymer. The resulting template may be used to direct self-assembly of a suitable self-assemblable polymer and the resulting aligned and oriented self-assembled polymer may itself be used as a resist for lithography of the substrate.

  • Patent number: 8602079
    Abstract: An apparatus for manufacturing a roller includes a loading plate, a polishing device, a processing device, a hot pressing device, a mounting device, and a cutting device. The loading plate loads a preprocessed metal plate having a preprocessed molding surface. The polishing device polishes the preprocessed molding surface to obtain a polished molding surface. The processing device forms molding patterns on the polished molding surface to obtain a metal plate with a molding surface defining the molding patterns. The hot pressing device forms impression patterns on a preprocessed resin film to obtain a resin film by pressing the metal plate and the preprocessed resin film together. The mounting device mounts the resin film to a rolling surface of a main body until the resin film winds around the rolling surface. The cutting device cuts the resin film.

  • Patent number: 8591787
    Abstract: A method of creating a foam pattern comprises mixing a polyol component and an isocyanate component to form a liquid mixture. The method further comprises placing a temporary core having a shape corresponding to a desired internal feature in a cavity of a mold and inserting the mixture into the cavity of the mold so that the mixture surrounds a portion of the temporary core. The method optionally further comprises using supporting pins made of foam to support the core in the mold cavity, with such pins becoming integral part of the pattern material simplifying subsequent processing. The method further comprises waiting for a predetermined time sufficient for a reaction from the mixture to form a foam pattern structure corresponding to the cavity of the mold, wherein the foam pattern structure encloses a portion of the temporary core and removing the temporary core from the pattern independent of chemical leaching.

  • Publication number: 20130309922
    Abstract: A swimming paddle with an upper rounded swimcap-shaped edge terminating in side indentations that define cap-securing temples, and a central goggle-securing notch cooperating with a concave region in the lower edge to store goggles vertically on the paddle. The paddle may further include fingerpad-indexing holes extending through the body of the paddle from the inner face to the outer face, the holes sized to allow only the fingerpads of a swimmer's extended fingers to partially protrude from the inner face. A method for custom fitting a swimming paddle to a particular swimmer's hand includes generating a side-by-side image of the swimmer's hand and a commonly-carried object such as a mobile phone in a common plane. The image is compared to stored dimensional data for the object to remotely determine the dimensions of the swimmer's hand and manufacture a custom paddle.

    Abstract: A surgical instrument comprising a symbol formed in or on a smooth surface surrounding the symbol, wherein the symbol comprises a plurality of angled surfaces over at least part of the area of the symbol, wherein the angled surfaces define a plurality of parallel ridges and grooves in the symbol. These ridges and grooves create an improved contrast for the symbol relative to the surrounding surface by a combination of different specular reflection of incident light compared to the surrounding surface and shadows formed by the ridges and grooves. A method of marking a surgical instrument with a symbol formed in or on a smooth surface is also described. The method comprises forming a symbol in or on a smooth surface of the surgical instrument; and forming a plurality of angled surfaces over at least part of the area of the symbol, wherein the angled surfaces define a plurality of parallel ridges and grooves in the symbol.
