Abstract
Airborne H2S contamination exists in cleanroom air, scanner tool environment, and facility CDA. It was confirmed by laser radiation test that H2S causes haze formation by reaction with O3, and therefore H2S in the ArF lithography environment should be controlled in the same way as SO2. It is necessary to select an adequate chemical filter to remove H2S effectively.
