Abstract

A radiation source for generating extreme ultraviolet radiation for a lithographic apparatus has a debris mitigation device comprising a nozzle arranged at or near an intermediate focus (IF) of the beam of radiation. The nozzle serves to direct a flow of gas (330) towards the radiation source or collector optic in order to deflect particulate debris (43) emitted by the radiation source.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Applications 61 / 313,452 and 61 / 348,477, filed March 12, 2010, and May 26, 2010, respectively, which are hereby incorporated by reference in their entirety. technical field [0003] The invention relates to a radiation source, in particular a radiation source for lithography, a lithographic apparatus and a method for manufacturing a device. Background technique [0004] A lithographic apparatus is a machine that applies a desired pattern to a substrate, usually a target portion of the substrate. A lithographic apparatus may be used, for example, in the manufacture of integrated circuits (ICs). In this case, a patterning device, alternatively referred to as a mask or reticle, may be used to generate the circuit pattern to be formed on the individual layers of the IC. The pattern can be transferred onto a target portion (eg, comprising a portion, one or more dies) on a ...
