    • The present invention relates to novel monomers for preparing photoresist polymers, polymers thereof, and photoresist compositions using the same. The monomers of the iinvention are represented by the following Chemical Formula 1: wherein, X and Y individually represent oxygen, sulfur, CH2 or CH2CH2; n is an integer of 1 to 5; and R1, R2, R3 and R4 individually represent hydrogen, C1-C10 alkyl having substituent(s) on its main or branched chain, C1-C10 ester having substituent(s) on its main or branched chain, C1-C10 ketone having substituent(s) on its main or branched chain, C1-C10 carboxylic acid having substituent(s) on its main or branched chain, C1-C10 acetal having substituent(s) on its main or branched chain, C1-C10 alkyl having substituent(s) including one or more hydroxyl group(s) on its main or branched chain, C1-C10 ester having substituent(s) including one or more hydroxyl group(s ) on its main or branched chain, C1-C10 ketone having substituent(s) including one or more hydroxyl group(s) on its main or branched chain, C1-C10 carboxylic acid having substituent(s) including one or more hydroxyl group(s) on its main or branched chain, or C1-C10 acetal having substituent(s) including one or more hydroxyl group(s) on its main or branched chain; provided that at least one of R1 to R4 represent(s) —COO—R′—OH wherein R′ is a linear or branched chain alkyl group with or without substituent(s) on its linear or branched chain. Polymers according to the present invention preferably comprise (i) a monomer of Chemical Formula 1 above as the first comonomer, (ii) a polyalicyclic derivative having one or more acid labile protective group(s) as the second comonomer, and (iii) at least one polymerization-enhancing monomer, preferably selected from the group consisting of maleic anhydride, maleimide derivatives, and combinations thereof. In order to increase photosensitivity, it is also preferable for the photoresist copolymer to comprise (iv) a polyalicyclic derivative having one or more carboxylic acid groups, as an additional comonomer.

    • The present invention provides a cross-linker monomer of formula 1, a photoresist polymer derived from a monomer comprising the same, and a photoresist composition comprising the photoresist polymer. The cross-linking unit of the photoresist polymer can be hydrolyzed (or degraded or broken) by an acid generated from a photoacid generator on the exposed region. It is believed that this acid degradation of the cross-linking unit increases the contrast ratio between the exposed region and the unexposed region. The photoresist composition of the present invention has improved pattern profile, enhanced adhesiveness, excellent resolution, sensitivity, durability and reproducibility. where A, B, R1, R2, R3, R4, R5, R6 and k are as defined herein.
    • 本发明提供了式1的交联剂单体,衍生自包含其的单体的光致抗蚀剂聚合物和包含光致抗蚀剂聚合物的光致抗蚀剂组合物。 光致抗蚀剂聚合物的交联单元可以通过暴露区域上的光致酸发生器产生的酸水解(或降解或破坏)。 据信交联单元的酸降解增加了曝光区域与未曝光区域之间的对比度。 本发明的光致抗蚀剂组合物具有改进的图案轮廓,增强的粘合性,优异的分辨率,灵敏度,耐久性和再现性。其中A,B,R1,R2,R3,R4,R5,R6和k如本文所定义。
