The interactions of sputter-deposited ruthenium with organosilicate glass(OSG) at 300 K have been studied by x-ray photoelectron spectroscopy (XPS)for Ru coverages from ∼ 0.1 monolayer to several monolayers, using in-situsample transfer between the deposition and analysis chambers. The resultsindicate Stranski-Krastanov (SK) type growth, with the completion of thefirst layer of Ru at an average thickness corresponding to 1 monolayeraverage coverage. Ru(0) is the only electronic state present. XPS core levelspectra indicate weak chemical interactions between Ru and the substrate. Aless pronounced tendency towards SK growth was observed for Ru deposition onparylene. Deposition of Ru on OSG followed by electroless deposition of Curesulted in the formation of a shiny copper film that failed the Scotch Tapetest. Results indicate failure mainly at the Ru/OSG interface.
