    • Disclosed herein is an organic anti-reflective coating polymer suitable for use in ultrafine pattern formation during fabrication of a semiconductor device. The organic anti-reflective coating polymer has a weight-average molecular weight of about 2,000 to about 100,000 and is represented by Formula 1 below: wherein R1 is a C1-C5 linear or branched alkyl group, R2 and R3 are each independently hydrogen or methyl, X is halogen, n is a number from 1 to 5, and a, b and c, representing the mole fraction of each monomer, are each independently from about 0.1 to about 0.9. Also disclosed are an organic anti-reflective coating composition comprising the coating polymer and a method for forming a photoresist pattern with the coating composition.
    • 本文公开了一种适用于半导体器件制造期间超细图案形成的有机抗反射涂层聚合物。 有机抗反射涂层聚合物的重均分子量为约2,000至约100,000,由下式1表示:其中R1为C1-C5直链或支链烷基,R2和R3各自独立地为氢或甲基 ,X为卤素,n为1〜5的数,代表各单体的摩尔分数的a,b和c各自独立地为约0.1〜约0.9。 还公开了包含涂料聚合物的有机抗反射涂料组合物和用该涂料组合物形成光致抗蚀剂图案的方法。
