Outline of Final Research Achievements

We tried to understand the precipitation mechanisms of silver crystal formed by solid-state ion exchange method assisted with forward/reverse voltage applications. The application of the precipitation layer to internal electrical wiring was also examined. The observation results showed that the silver precipitates developed during reverse voltage application by the electrical reduction of silver ions which were doped with forward voltage application. The reverse voltage application after repeated doping of silver and sodium ions enabled to form multi-layered silver wiring in the glass substrate. We also formed fine internal electrical paths below 0.1 mm of line width by using printed silver nano-ink as a silver ion source.
