Herein, we report on fabrication of silver (Ag) microwiring on a double-decker-shaped polysilsesquioxane (DDPSQ) hybrid film by laser direct writing using an Ag nanoparticle dispersed film as a precursor. The line width of the Ag-wiring fabricated by this technique can be controlled flexibly by changing the objective lens magnification and the focusing point. Using an objective lens magnification lOOx, Ag microwiring with a line width of about 5//m has been obtained. The Ag-wiring shows an excellent adherence to DDPSQ surface as evaluated by Scotch- tape test. The resistivity of the Ag-wiring is determined to be about 4.3 x 10-6 cm. This value is almost comparable with the resistivity of bulk Ag (1.6 x 10-6 cm).
