Laser-induced direct writing of silver lines on a ferrite surface from a silver acetate (CH3COOAg) thin layer has been investigated. The deposition is a thermochemical process and the threshold temperature for thermal decomposition of CH3COOAg is about 380° C. About 100% of Ag in the deposited lines has been achieved. The width of the deposited Ag-lines increased with the increase in laser power, and it can be accurately estimated by the temperature profile induced by laser irradiation within the power region below the melting point of ferrite. A line thickness of micron order can be formed both on a ferrite surface and on a deposited SiO2 surface, whereas the line width decreased with the increase in beam dwell time due to the vaporization of both CH3COOAg precursor and deposited Ag material.
