    Abstract: PROBLEM TO BE SOLVED: To provide a method for cleaning elements of a lithographic device, especially a method for cleaning one or more optical elements of the lithographic device. SOLUTION: This method for cleaning elements of the lithographic device, for example, optical elements such as a collector mirror, includes a step for supplying gas containing nitrogen, a step for forming a radical-containing gas by generating nitrogen radicals from at least a part of the gas containing nitrogen, and a step for supplying at least a part of the radical-containing gas to one or more elements of the lithographic device. The lithographic device comprises a source, an optical element and an electrical discharge generator arranged to generate a radio frequency discharge. COPYRIGHT: (C)2007,JPO&INPIT
