| 摘要 |
Filters for EUV lithography, methods of manufacture thereof, and methods of filtering in an EUV lithography system are disclosed. The filter comprises a nanotube material layer sandwiched by two thin material layers that are highly transmissive and provide structural support for the nanotube material layer. The filter is supported on at least one side by a patterned structural support. The filter mitigates debris, provides spectral purity filtering, or both.
