  • Patent number: 8934259
    Abstract: A method for fabricating a substrate having transferable chiplets includes forming a photo-sensitive adhesive layer on a process side of a source substrate including active components or on a patterned side of a transparent intermediate substrate. The intermediate substrate is brought into contact with the source substrate to adhere the active components on the process side to the patterned side of the intermediate substrate via the photo-sensitive adhesive layer therebetween. Portions of the source substrate opposite the process side thereof are removed to singulate the active components. Portions of the photo-sensitive adhesive layer are selectively exposed to electromagnetic radiation through the intermediate substrate to alter an adhesive strength thereof. Portions of the photo-sensitive adhesive layer having a weaker adhesive strength are selectively removed to define breakable tethers comprising portions of the adhesive layer having a stronger adhesive strength.

  • Patent number: 8703406
    Abstract: A method of forming a master from smaller originals is provided for use in replicating molecular transfer lithography (M×L) templates, cured polymer films for imprinting molds or cured polymer films for photonic applications. A coating layer on a base substrate is successively patterned in two or more areas using dissoluble conformal templates created from original master patterns, wherein areas not being patterned with a template at any given stage of the process are protected with photoresist and templates applied to open areas also partially overlap the resist-protected areas. Overlapping minimizes seam formation in the overall pattern. Templates have etch-resistant functional material that adheres to the coating layer on the base substrate. After dissolving the template to leave only the functional material in the pattern of the original master, etching of the coating layer transfers the pattern to the etched coating layer of the base substrate.

    Abstract: Examples of novel semiconductor processing pedestals, and apparatuses including such pedestals, are described. These pedestals are specifically configured to provide uniform heat transfer to semiconductor substrates and to reduce maintenance complexity and/or frequency. Specifically, a pedestal may include a removable cover positioned over a metal platen of the pedestal. The removable cover is configured to maintain a consistent and uniform temperature profile of its substrate-facing surface even though the platen's upper-surface, which supports the cover and is in thermal communication with the cover, may have a much less uniform temperature profile. The cover may be made from certain ceramic materials and shaped as a thin plate. These materials are resistant to the processing environments and maintain their thermal characteristics over many processing cycles. The cover can be easily removed from the platen and replaced with a new one without a need for major disassembly of the entire apparatus.

  • Patent number: 6893802
    Abstract: In a method of forming a patterned thin film, a first film to be patterned and a peelable film are sequentially formed on a base layer, and an undercut mask is then formed thereon. Then, using of the mask, the peelable film and the first film to be patterned are etched selectively to form a first patterned thin film. During the etching, a substance that forms the first film to be patterned deposits to form a deposition film on the peelable film. Then, a film to be patterned is formed over the entire surface. During the formation, a substance that forms the film to be patterned deposits to form another deposition film on the peelable film. The mask and the peelable film are then peeled off to remove the deposition films together.

  • Patent number: 6723479
    Abstract: The invention relates to a method of providing a decorative coating or text or the like on articles, like shavers, GSM's, cards, etc. The coating comprises a region-wise optically modified (patterned) cholesteric liquid crystalline layer, which is transferred onto a surface of the article by means of a transfer operation. The so-called in-mold decoration technique has been found to be very advantageous for the transfer of decorative (patterned) cholesteric liquid crystalline layers. In this technique the layer is (releasably) deposited on a plastic carrier foil and provided with a layer of adhesive. The assembly is inserted in an injection mold before the injection molding of polymer material starts. In this way decorative coatings (e.g. multi color images) and texts or the like can be even applied onto, non-even and slightly curved substrates.
