Method for obtaining an extreme ultraviolet radiation source, radiation source and use in lithography

摘要

Method for obtaining extreme ultraviolet radiation and a source thereof, application in lithography. According to the invention, at least a solid target ( 28 ) is used, emitting extreme ultraviolet radiation by interaction with a laser beam focussed on a face ( 30 ) of the target. This target is able to emit a portion of the radiation from the opposite face ( 37 ) and this portion is collected and transmitted.
