Microelectronic-grade copper foils were immersion silver plated in ahome-made non-cyanide alkaline silver nitrate - thiosulfate solution and in twocommercially available industrial baths via contact reductive precipitation.The concentration depth profiles of the freshly deposited silver layers wereafterwards analyzed at nanoscale resolution by means of Secondary Neutral MassSpectrometry (SNMS) and Glow Discharge Optical Emission Spectroscopy (GDOES).The thickness of deposited silver layers obtained with 30-60 s immersion timewere in the range of 50-150 nm, depending on the parameters of the immersionprocedure. Slight contamination of sulfur from the thiosulfate bath wasdetectable. Traces of Cr and Na could be observed as well around the interfacebetween the copper substrate and silver deposit. Results also indicate thatstorage for longer time in air especially at higher than ambient temperaturesinduces a kind of ageing effect in the deposited layer, changing itscomposition. In case of samples prepared from home-made solution increasingamounts of copper together with its corrosion products became detectable.
