Abstract

Continuous silver microstructures were produced by three-dimensional (3-D) direct laser writing using a femtosecond-pulsed laser beam with polyvinylpyrrolidone (PVP) films containing silver ions. The lines drawn by scanning a tightly focused laser beam ranged from 200 nm to 1.7 µm. Using a sample solution of high density of silver nitrate, a continuous silver line with a resistivity of 3.48×10-7 Ωm was produced. Not only 3-D microstructures such as pyramidal models but also hybrid microstructures comprising polymer and silver lines were demonstrated. The 3-D direct laser writing of metallic microstructures has potential for application to 3-D electrical wiring of electronic devices and MEMS devices.
