    摘要: New photoresist compositions are provided that are useful for immersion lithography. In one preferred aspect, photoresist composition are provided that comprise: (i) one or more resins that comprise photoacid-labile groups, (ii) a photoactive component, and (iii) one or more materials that comprise photoacid labile groups and that are distinct from the one or more resins; wherein the deprotection activation energy of photoacid-labile groups of the one or more materials is about the same as or lower than the deprotection activation energy of photoacid-labile groups of the one or more resins. In another preferred aspect, photoresist compositions are provided that comprise (i) one or more resins, (ii) a photoactive component, and (iii) one or more materials that comprise a sufficient amount of acidic groups to provide a dark field dissolution rate of at least one angstrom per second.

    摘要: New photoresist compositions are provided that are useful for immersion lithography. Preferred photoresist compositions of the invention comprises two or more distinct materials that can be substantially non-mixable with a resin component of the resist. Particularly preferred photoresists of the invention can exhibit reduced leaching of resist materials into an immersion fluid contacting the resist layer during immersion lithography processing.
