  • Publication number: 20120256333
    Abstract: A process for manufacturing stand-alone multilayer thin films is provided. The process includes providing a substrate, depositing a sacrificial layer onto the substrate and the depositing multilayer thin film onto the sacrificial layer. Thereafter, the substrate, sacrificial layer and thin film structure are exposed to chemical solutions. The chemical solution selectively reacts with the sacrificial layer to remove the sacrificial layer, thereby affording for an intact multilayer stand-alone thin film to separate from the substrate. The color and optical properties of the multilayer thin film are not affected by the removal of the sacrificial layer.

  • Publication number: 20120153527
    Abstract: A process for manufacturing stand-alone thin films is provided. The process includes providing a substrate, depositing a carbon-containing sacrificial layer onto the substrate and the depositing a thin film onto the carbon-containing sacrificial layer. Thereafter, the substrate, carbon-containing sacrificial layer and thin film structure are exposed to oxygen at an elevated temperature. The oxygen reacts with the carbon-containing sacrificial layer to produce carbon dioxide and remove carbon from the sacrificial layer, thereby generally burning away the sacrificial layer and affording for an intact stand-alone thin film to separate from the substrate.
