Patent number: 12237166Abstract: 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.
