- A high density of Pd catalytic particles is an important factor for obtaining a uniform and continuous Ag seed layer in electroless
plating. Adequate surface pretreatment is critical for the formation of such a Pd catalytic particle population. In this study,
electroless plating of Ag thin films on TiN substrates was performed using Sn sensitization and Pd activation as pretreatment
methods. Sn surface sensitization improves surface wetting and aids in the formation of a Pd catalytic layer in surface-oxidative
Pd activation. The Pd activation supported by Sn sensitization also accelerated the formation of a continuous thin Ag film.
Furthermore, a thin Ag seed layer deposited on a patterned structure showed excellent conformality.
