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 comprise one or more materials that have base-reactive groups and are particularly useful for dry lithography. Particularly preferred photoresists of the invention can exhibit reduced defects following development of a coating layer of the resist.
摘要:
New nitrogen-containing compounds are provided that comprise multiple hydroxyl moieties and photoresist compositions that comprise such nitrogen-containing compounds. Preferred nitrogen-containing compounds comprise 1) multiple hydroxyl substituents (i.e. 2 or more) and 2) one or more photoacid-labile groups.
摘要:
A photoacid generator has the formula (I): wherein R1, R2, R3, L1, L2, L3 X, Z+, a, b, c, d, p, q, and r, are defined herein. A photoresist comprises the photoacid generator, and a coated article comprises the photoresist. The photoresist can be used to form an electronic device.
摘要:
This invention relates to new photoacid generator compounds and photoresist compositions that comprise such compounds. In particular, the invention relates to photoacid generator compounds that comprise a multi cyclic lactone moiety.
摘要:
New photoresist compositions are provided that are useful for immersion lithography. Preferred photoresist compositions of the invention comprise one or more materials that have sugar substitution. 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.
摘要:
New bis(sulfonyl)imide and tri(sulfonyl)methide photoacid generator compounds (“PAGs”) are provided as well as photoresist compositions that comprise such PAG compounds.
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.
