There is provided a pattern forming method comprising (a) a step of forming a film on a substrate using an electron beam-sensitive or extreme ultraviolet radiation-sensitive resin composition, (b) a step of forming a top coat layer on the film using a top coat composition containing a resin (T) containing at least any one of repeating units represented by formulae (I-1) to (I-5) shown below, (c) a step of exposing the film having the top coat layer using an electron beam or an extreme ultraviolet radiation, and (d) a step of developing the film having the top coat layer after the exposure to form a pattern.
提供了一种图案形成方法,包括以下步骤:(a)使用电子束敏感或极紫外辐射敏感的树脂组合物在基板上形成薄膜的步骤,(b)使用含有至少一个由下式(I-1)到(I-5)中所示的重复单元表示的树脂(T)的顶层涂料组成的顶层涂料层的形成步骤,(c)使用电子束或极紫外辐射照射具有顶层涂料层的薄膜的步骤,以及(d)在照射后开发具有顶层涂料层的薄膜以形成图案的步骤。
