Abstract With as-prepared silver based ink or as raw materials, the patterned silver electrodes with high conductivity and flatness were fabricated via laser direct writing (LDW) followed by transfer process, and the laser direct writing, work function adjustment and transfer process of silver electrodes were investigated in detail. The silver electrode with a sheet resistance of 0.9 Ω·sq−1 can be obtained after LDW at laser power of 3 W and scanning speed of 2.5 cm·s−1, and the work function can be adjusted by mixing zinc acetate or chlorogold acid into the precursor silver ink. After transfer process, the flatness of the electrodes reaches to 4.2 nm in the range of 1 × 1 μm2. This LDW preparation followed by transfer process is an appropriate approach to prepare high conductive patterned silver electrode for electronic devices.
