摘要： A pattern forming method includes (a) coating a substrate with a resist composition including a resin that includes a repeating unit represented by a following general formula (NGH-1), and, by the action of an acid, increases the polarity and decreases the solubility in a negative developing solution; (b) exposing; and (d) developing with a negative developing solution: wherein RNGH1 represents a hydrogen atom or an alkyl group; and RNGH2 to RNGH4 each independently represents a hydrogen atom or a hydroxyl group, provided that at least one of RNGH2 to RNGH4 represents a hydroxyl group.

摘要翻译： 图案形成方法包括：（a）用包含由以下通式（NGH-1）表示的重复单元的树脂的抗蚀剂组合物涂布基材，并且通过酸的作用增加极性，并降低 在负显影液中的溶解度; （b）曝光; 和（d）用负显影液显影：其中RNGH1表示氢原子或烷基; 并且RNGH 2至RNGH 4各自独立地表示氢原子或羟基，条件是RNGH 2至RNGH 4中的至少一个表示羟基。
