Abstract

The invention relates to a method for cleaning surfaces (1) of a component (2), in particular for removing contaminants (3), further especially filmic and / or organic contaminants, from surfaces of mechanical assemblies of a lithography system, comprising at least the following steps in the specified order: (a) cleaning the surface (1) using a CO2 snow jet; (b) optically inspecting the surface (1) to locate any contaminants (3) that may still be remaining after step (a), in particular fluorescent ones; and (c) cleaning the surface (1) by removing the contaminants (3) located in step (b) using a laser beam and / or ozone.
