The present invention relates to: a resist composition such as a chemically amplified resist composition for providing an excellent pattern profile even at a substrate-side boundary face of resist, in addition to a higher resolution in photolithography for micro-fabrication, and particularly in photolithography adopting, as an exposure source, KrF laser, ArF laser, F

laser, ultra-short ultraviolet light, electron beam, X-rays, or the like; and a patterning process utilizing the resist composition. The present invention provides a chemically amplified resist composition comprising one or more kinds of amine compounds or amine oxide compounds (except for those having a nitrogen atom of amine or amine oxide included in a ring structure of an aromatic ring) at least having a carboxyl group and having no hydrogen atoms covalently bonded to a nitrogen atom as a basic center.
本发明涉及一种抗蚀组合物,例如用于在抗蚀物的基板侧边界面上提供优异图案轮廓的化学增感抗蚀组合物,除了在微细加工的光刻工艺中具有更高的分辨率外,特别是在采用KrF激光、ArF激光、F2激光、超短紫外光、电子束、X射线等作为曝光光源的光刻工艺中;以及利用该抗蚀组合物的图案化工艺。本发明提供一种化学增感抗蚀组合物,其包括一种或多种胺化合物或胺氧化合物(除了那些在芳香环的环结构中不含有胺或胺氧原子的氮原子的化合物),至少具有一个羧基,并且没有氢原子共价键结合到氮原子作为碱性中心。
