Abstract: The present disclosure provides new processes and methods to pre-treat metal surfaces in the back end of line (BEOL) fabrication of integrated circuits (ICs). More specifically, the present disclosure provides selective, self-limiting processes and methods for stripping native oxide surface layers that may form on exposed metal surfaces during processing of ICs. The processes and methods disclosed herein utilize the fundamental concepts of metal complexation to provide a novel solution, which enables native oxide surface layers to be selectively removed from exposed metal films in a self-limiting manner. In particular, the disclosed processes and methods use complexing agents (e.g., ligands) to selectively dissolve native oxide surface layers, without significantly etching or removing the underlying metal film.
