  • Patent number: 10366887
    Abstract: The present invention is broadly concerned with materials, processes, and structures that allow an underlayer to be imaged directly using conventional lithography, thus avoiding the photoresist processing steps required by prior art directed self-assembly (DSA) processes. The underlayers can be tailored to favor a selected block of the DSA block co-polymers (BCP), depending on the pattern, and can be formulated either to initially be neutral to the BCP and switch to non-neutral after photoexposure, or can initially be non-neutral to the BCP and switch to neutral after exposure. These materials allow fast crosslinking to achieve solvent resistance and possess good thermal stability.

  • Patent number: 10160143
    Abstract: A column or other elongate molded part is molded using an elongate tubular mold having a closed end, an open end and a flexible sidewall. After the column or other molded part is formed, it is extracted from the mold by pulling the column or other molded part axially through the open end of the mold. The inner surface of the mold may comprise a recessed or protruding form to mold a protruding or sunken relief on or in an exterior surface of the molded part. The column may be extracted using an expandable plug that is inserted into the interior of the column or other molded part through the open end of the mold. The expandable plug is expanded to engage and seal against an inner surface of the elongate molded part. A pressurized gas is introduced into the interior of the elongate molded part through the plug to expand the mold before pulling the column through the open end of the mold.

  • Patent number: 8529795
    Abstract: A method of preparing a wet-processible metal oxide solution and a method of fabricating a film using the same are provided. A metal oxide that has been widely used as a photocatalyst is improved and a metal oxide solution having new functionality is formed. The metal oxide solution is transparent, wet-processible, and facilitates electron transfer. The metal oxide solution can be applied in various ways to an electronic device and is well-suited for application to an electronic device using organic materials. Also, a titanium oxide solution functions to remove and block oxygen and moisture. Thus, when it is applied to an electronic device using organic materials that are vulnerable to oxygen and moisture, the lifetime of the device can be increased.

  • Patent number: 8480937
    Abstract: A method of forming a simulated combustible fuel element including covering at least a part of a surface of a master with a material selected to produce a mold, and then removing the master from the mold. A predetermined amount of a liquefied body material that is less than a volume of the mold is introduced into the mold. A body including the body material is produced with one or more cavities therein and an exterior surface simulating at least the part of the surface of the master. The body material is allowed to solidify, at least to the extent that the body material is self-supporting, and the mold and the body are separated. One or more fuel light sources are positioned to direct light therefrom in the cavity. At least a portion of the exterior surface is coated so that the portion simulates a combustible fuel element.

  • Patent number: 8480936
    Abstract: A method for fabricating a mold includes the steps of forming a photo-polymerizable resin layer between a master substrate and a transparent mold substrate, wherein a first pattern is formed on the master substrate; solidifying the resin layer by exposing the resin layer to a UV light through the transparent mold substrate; and forming a mold having a second pattern by separating the resin layer from the master substrate, wherein the second pattern is in a form of a recess on the resin layer at a portion corresponding to the first pattern and the resin layer being engaged with the mold substrate.

  • Publication number: 20130122135
    Abstract: Stamp for microcontact printing. The stamp includes a bulk portion having first and second surfaces, the first surface including a pattern of features to be transferred and the second surface including a different pattern of features. The features on the second surface have a lower stiffness than the features on the first surface. The dual-face stamp design of the invention provides an alternative location for dimensional errors to be absorbed, making microcontact printing a more robust production process.

  • Publication number: 20130101792
    Abstract: The present invention solves numerous problems in state-of-the-art industrial polymer shaping of micro and nanostructures. The problems of high tool polishing requirements, the inability to define an arbitrary topographical structure on an arbitrary free-form (curved) surface, limited durability and replication quality, as well as providing a convenient method for functionalizing the surface. The invention solves these problems by deploying a ceramic material precursor, which may be coated onto a conventional polymer shaping tool, micro- or nanostructured by mechanical contact (embossing), cured into a hard, durable ceramic material comprising the desired structures. The ceramic material is functionalisable by silane chemistry, due to its high surface density of —OH groups. This apparatus may then be used in a conventional polymer shaping process to make nanostructured polymer replicas.

    Abstract: According to an embodiment, a method of forming a film is provided. In the method of forming a film, a reversed pattern which is the reverse of a desired layout pattern is formed on a first substrate. Subsequently, a pattern material of the desired layout pattern is supplied to a second substrate as a reversal material. Thereafter, the reversed pattern is brought into contact with the reversal material such that the reversed pattern faces the reversal material, so that the reversed pattern is filled with the reversal material by a capillary phenomenon.
