| 摘要 |
The present invention provides methods for lithography utilizing X-ray radiation. More particularly, the methods of the invention can be employed for lithography at wavelengths in a range between about 0.8 nm and 30 nm, and more particularly, at wavelengths in a range between 0.8 and 1.2 nm. The methods of the invention employ photoresist compositions having fluorinated polymers with a fluorine content of at least about 10% by weight to provide enhanced sensitivity for X-ray lithography.
