Abstract
The nano-scale metallization of Au on flexible polyimide substrate by reversal imprint and lift-off process was investigated. The nano-scale mold was fabricated; the anti-adhesion property of nanometer-size Si-mold was improved and the surface free energy was calculated with the contact angle measurement. The ∼150 nm width Au nano-wires were successfully fabricated on Si and on flexible polyimide substrate with the proposed process. The PMMA thickness dependent trend with reversal imprinting and Au nano-wires lift-off results were also investigated by SEM analysis.
