    Abstract: The present disclosure relates to semiconductor device manufacturing, and particularly to selective metal wet etching compositions and processes for selectively etching certain metals relative to adjacent structures and materials with those etching compositions. More particularly, the present disclosure relates to aqueous metal passivation and etching compositions, as well as to processes of using these compositions in the presence of nickel platinum silicides. This disclosure further relates to a passivation composition containing at least one sulfonic acid, at least one compound containing a nitrate or nitrosyl ion, and water, wherein the passivation composition is substantially free of a halide ion.
