    • A composition for forming an upper layer film for immersion exposure. It can form an upper layer film effectively inhibited from developing defects through an immersion exposure process, such as a watermark defect and dissolution residue defect. Also provided are an upper layer film for immersion exposure and a method of forming a resist pattern. The composition for forming an upper layer film comprises a resin ingredient and a solvent. The resin ingredient comprises a resin comprising at least one kind of repeating units selected among those represented by the formulae (1-1) to (1-3) and at least either of the two kinds of repeating units represented by the formulae (2-1) and (2-2). (1-1) (1-2) (1-3) (2-1) (2-2). [In the formulae, Rrepresents hydrogen or methyl; Rand Reach represents methylene, linear or branched Calkylene, or alicyclic Calkylene; Rrepresents hydrogen or methyl; and Rrepresents a single bond, methylene, or linear or branched Calkylene]
    • 一种用于形成浸渍曝光用上层膜的组合物。 可以通过浸没曝光工艺(如水印缺陷和溶解残留缺陷)形成上层膜,从而有效抑制显影缺陷。 还提供了用于浸渍曝光的上层膜和形成抗蚀剂图案的方法。 用于形成上层膜的组合物包括树脂成分和溶剂。 树脂成分包含由式(1-1)〜(1-3)表示的重复单元中选出的至少一种重复单元和由式(2-1)表示的两种重复单元中的至少一种的树脂, 1)和(2-2)。 (1-1)(1-2)(1-3)(2-1)(2-2)。 [式中,R代表氢或甲基; Rand Reach表示亚甲基,直链或支链C亚烷基或脂环族C亚烷基; 表示氢或甲基; 并且R表示单键,亚甲基或直链或支链C亚烷基]
