A cleaning composition for cleaning particulate contamination from small dimensions on microelectronic device substrates. The cleaning composition contains dense CO2 (preferably supercritical CO2 (SCCO2)), alcohol, fluoride source, anionic surfactant source, non-ionic surfactant source, and optionally, hydroxyl additive. The cleaning composition enables damage-free, residue-free cleaning of substrates having particulate contamination on Si/SiO2 substrates. |
