  • Publication number: 20200381647
    Abstract: A method of flash-curing a respective layer in an electronic device stack is provided. The method includes providing a stack of layers including a substrate and one or more electronically-active layers disposed on a surface of the substrate. The method further includes applying, over the stack of layers, a thermally-curable layer of material that includes a polymer or polymerizable material. The method further includes performing a non-equilibrium thermal process that includes raising a temperature of the thermally-curable layer of material, including the polymer or polymerizable material, above a first temperature for a length of time sufficient to cure the thermally-curable layer of material while maintaining the stack of layers below a second temperature that is less than the first temperature. The stack of layers is robust to temperatures below the second temperature.

  • Publication number: 20200371615
    Abstract: A method of fabricating a composite conductive film is provided. The method includes providing, as a matrix, a layer of photoresist material. The method further includes introducing a plurality of inorganic particles upon a surface of the layer of photoresist material. The method further includes, without patterning the layer of photoresist material, embedding at least some of the plurality of inorganic particles into the layer of photoresist material to form an inorganic mesh within the layer of photoresist material, thereby forming the composite conductive film. Embedding at least some of the plurality of inorganic particles into the layer of photoresist material results in the composite conductive film being patternable and substantially transparent to optical light.

  • Patent number: 10234969
    Abstract: A method of fabricating a composite conductive film is provided. The method includes providing, as a matrix, a layer of cross-linkable polymer, where the cross-linkable polymer is in a non-cross-linked state. The method further includes introducing inorganic nanowires upon a surface of the layer of cross-linkable polymer. The inorganic nanowires are, in isolated form, characterized by a first conductivity stability temperature. The method further includes embedding at least some of the inorganic nanowires into the layer of cross-linkable polymer to form an inorganic mesh, thereby forming the composite conductive film. The method further includes cross-linking the polymer within a surface portion of the composite conductive film. Cross-linking the polymer within the surface portion of the composite conductive film results in the surface portion having a second conductivity stability temperature that is greater than the first conductivity stability temperature.
