Laser printing and sintering of Zn nanoparticles for bioresorbable electronics (Conference Presentation)
Author(s): Heng Pan

Paper Abstract

Bioresorbable electronic devices are currently fabricated by complex and expensive vacuum-based Integrated Circuits (IC) processes. In this paper, we report a low-cost manufacturing approach for bioresorbable conductors on bioresorbable polymer substrates by evaporation-condensation-mediated laser printing and sintering of Zn nanoparticle. Laser sintering of Zn nanoparticles has been technically difficult due to the readily formation of surface oxide. We report a novel way to print and sinter Zn nanoparticle on low temperature substrate facilitated by evaporation-condensation in confined domain. This new approach circumvents the surface oxide, which notoriously hinders the nanoscale sintering process. The entire metallization process can be realized in non-vacuum environment allowing easy integration on a roll-to-roll production platform for economical manufacturing of bioresorbable electronics.
