    Abstract: A conductive metal pattern is formed in a polymeric layer that has a reactive polymer that comprises (1) pendant groups that are capable of providing pendant sulfonic acid groups upon exposure to radiation, and (2) pendant groups that are capable of reacting in the presence of the sulfonic acid groups to provide crosslinking. The polymeric layer is patternwise exposed to provide a polymeric layer comprising non-exposed regions and exposed regions comprising a polymer comprising pendant sulfonic acid groups. The exposed regions are contacted with electroless seed metal ions to form a pattern of electroless seed metal ions. The electroless seed metal ions are reduced to provide a pattern of electroless seed metal nuclei that are then electrolessly plated with a conductive metal.

  • Patent number: 9034570
    Abstract: Some embodiments include methods of forming patterns of openings. The methods may include forming spaced features over a substrate. The features may have tops and may have sidewalls extending downwardly from the tops. A first material may be formed along the tops and sidewalls of the features. The first material may be formed by spin-casting a conformal layer of the first material across the features, or by selective deposition along the features relative to the substrate. After the first material is formed, fill material may be provided between the features while leaving regions of the first material exposed. The exposed regions of the first material may then be selectively removed relative to both the fill material and the features to create the pattern of openings.

    Abstract: A photochemical process for decorating hydrophobic surfaces with nanoparticles includes the steps of providing a metal precursor having hydrophobic parts adapted to interact with assistance of a photosensitizer; and forming a reactive adduct photosensitizer/precursor-metal/surface, preparing the surface to grow metal nanoparticles in situ having sizes and shapes governed by the morphology of the surface. The formed nanoparticles are sufficiently isolated, not aggregated and not interconnected, and do not create a film but maintain the chemical properties of substrate and metal. Surfaces so selectively decorated have hydrophobic properties even with hydrophilic substrates. Substrates with multiple chemical functionalities are thereby obtained, which can selectively bind different molecules or biomolecules onto the substrate and the surface of the metal nanoparticles surface. A process according to the invention also allows decorating surfaces with two or more metallic species.

A solution comprising the material capable of self-assembly and the organic casting solvent is casted on the patterned photoresist layer. Upon removal of the organic casting solvent, the material self-assembles, thereby forming the layered structure.

  • Publication number: 20140242524
    Abstract: A negative electrophoretic photoresist is applied over a plurality of protruding disposable template portions on a substrate. A silo structure is placed on planar portions of the negative electrophoretic photoresist that laterally surround the plurality of protruding disposable template portions. The negative electrophoretic photoresist is lithographically exposed employing the silo structure and a first lithographic mask, which includes a transparent substrate with isolated opaque patterns thereupon. After removal of the silo structure, the negative electrophoretic photoresist is lithographically exposed employing a second lithographic mask, which includes a pattern of transparent areas overlying the planar portions of the negative electrophoretic photoresist less the areas for bases of metal structure to be subsequently formed by electroplating. The negative electrophoretic photoresist is developed to form cavities therein, and metal structures are formed by electroplating within the cavities.

  • Publication number: 20140242525
    Abstract: A method of patterning a conductive polymer includes providing a conductive polymer layer coated over a first support followed by pattern-wise transferring a layer containing polyvinyl acetal from a second support onto the conductive polymer to form a mask with at least one opening. The masked conductive polymer is subjected to treatment through the opening that changes the conductivity of the conductive polymer by at least one order of magnitude in areas not covered by the mask.

  • Patent number: 8765359
    Abstract: Methods of preparing organosilane-functionalized regions on a substrate surface and more specifically fabricating patterned functionalized substrates suitable to be optically read, the methods generally comprising employing a vapor deposition process of an organosilane gas onto a lithographically patterned silicon surface followed by removal of the patterning media in a bath of organic solvents and ultrasonic excitation. The inventive methods provide optimized surface density of functional species while avoiding deleterious effects that can occur when lithographically patterned substrates are exposed to various gaseous species during the functionalization process.
