Title:
EUVリソグラフィシステムにおける光学素子寿命の延長
Document Type and Number:
Japanese Patent JP7337819
Kind Code:
B2
Abstract:
Degradation of the reflectivity of one or more reflective optical elements in a system for generating EUV radiation is reduced by the controlled introduction of a gas into a vacuum chamber containing the optical element. The gas may be added to the flow of another gas such as hydrogen or alternated with the introduction of hydrogen radicals.
