A pattern forming method includes coating an actinic ray-sensitive or radiation-sensitive resin composition onto a substrate to form an actinic ray-sensitive or radiation-sensitive film, coating a composition for forming a protective film onto the actinic ray-sensitive or radiation-sensitive film to form a protective film, exposing the actinic ray-sensitive or radiation-sensitive film covered with the protective film, and developing the exposed actinic ray-sensitive or radiation-sensitive film using a developer containing an organic solvent, in which the protective film contains a compound (A) including at least one group or bond selected from the group consisting of an ether bond, a thioether bond, a hydroxyl group, a thiol group, a carbonyl bond, and an ester bond, and a resin (X).
一种图案形成方法包括将感光或感辐射树脂组合物涂布到基底上以形成感光或感辐射胶片,将用于形成保护膜的组合物涂布到感光或感辐射胶片上以形成保护膜,曝光覆盖有保护膜的感光或感辐射胶片、使用含有有机溶剂的显影剂对曝光的感光胶片或辐射敏感胶片进行显影,其中保护膜含有一种化合物 (A),该化合物包括至少一个选自由醚键、硫醚键、羟基、硫醇基、羰基键和酯键组成的基团或键,以及一种树脂 (X)。
