  • Patent number: 11474430
    Abstract: The present disclosure relates to novel multiple trigger monomer containing negative working photoresist compositions and processes. The processes involve removing acid-labile protecting groups from crosslinking functionalities in a first step and crosslinking the crosslinking functionality with an acid sensitive crosslinker in a second step. The incorporation of a multiple trigger pathway in the resist catalytic chain increases the chemical gradient in areas receiving a low dose of irradiation, effectively acting as a built in dose depend quencher-analog and thus enhancing chemical gradient and thus resolution, resolution blur and exposure latitude. The photoresist compositions utilize novel monomers and mixtures of novel monomers. 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.

  • Patent number: 9383646
    Abstract: The present disclosure relates to novel two-step photoresist compositions and processes. The processes involve removing acid-labile groups in step one and crosslinking the remaining material with themselves or added crosslinking systems in step two. The incorporation of a multistep pathway in the resist catalytic chain increases the chemical gradient in areas receiving a low dose of irradiation, effectively acting as a built in dose depend quencher-analog and thus enhancing chemical gradient and thus resolution. The 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. Dual functionality photosensitive compositions and methods are also disclosed.
