Abstract: A method for cleaning silicon-containing deposits in process chamber is described. Fluorine-containing compounds and additional compounds are used for the cleaning. The deposits are removed using a cleaning gas contains fluorine-containing compounds, at least 50% of which have more than one carbon atom and are C 4 F 8 or C 2 F 6 molecules, and additional compounds, at least 50% of which have at least one oxygen atom and at least 50% are N 2 O molecules. A pressure in the chamber is between 266 Pa and 665 Pa. The method permits economical and environmentally friendly cleaning of the process chamber.
