Abstract

In the present study, the adhesion and thermal properties of the electroless-deposited Cu thin film were investigated. The multilayered structure of Cu/TaN/Si was fabricated by electroless-depositing the Cu thin layer on the TaN diffusion barrier which was deposited by MOCVD on the Si substrate. Crystallization and agglomeration of the electroless-deposited Cu film occurred through annealing in H2 atmosphere and resulted in a decrease of film resistance. Thermal stability of Cu/TaN/Si system was maintained up to the annealing temperature of 600°C in H2 atmosphere above which the intermediate compound of Cu-Si was formed through diffusion into the TaN layer. The adhesion of the electroless-deposited Cu film was compared with other deposition methods of thermal evaporation and sputtering. The scratch test showed that the adhesion of electroless plated Cu film on TaN was better than those of sputtered Cu film and evaporated Cu film.
