Abstract
An extreme ultraviolet (EUV) photolithography system detects debris travelling from an EUV generation chamber to a scanner. The photolithography system includes a detection light source and a sensor. The detection light source outputs a detection light across a path of travel of debris particles from the EUV generation chamber. The sensor senses debris particles by detecting interaction of the debris particles with the detection light.
