Zusammenfassung:The present disclosure relates to novel methanofullerene derivatives, negative- type photoresist compositions prepared therefrom and methods of using them. The derivatives, their photoresist compositions and the methods are ideal for fine pattern processing using, for example, ultraviolet radiation, beyond extreme ultraviolet radiation, extreme ultraviolet radiation, X-rays and charged particle rays.
