    • A method for forming a pattern comprises the steps of: generating an acid through exposure, forming a photosensitive resin film on a support body by using a photosensitive resin composite having solubility that is varied with respect to a developing solution through acid behavior, exposing the photosensitive resin film to light, and developing the exposed photosensitive resin film as a negative by using a developing solution containing an organic solvent to form a free pattern (1); applying a surface treatment reagent on the support body on which the free pattern is formed, and heating the support body on which the surface treatment reagent is applied to form a neutralization film (2); and alkali-developing the free pattern and the neutralization film that are formed on the support body, removing the free pattern from the support body, and forming a pattern formed of the neutralization film on the support body (3). The photosensitive resin composite used in the method for forming the pattern contains a base component (A) having reduced solubility with respect to the organic solvent through acid behavior, and the base component (A) contains a high molecule compound (A1) having a constituent unit (a2-1) that contains a lactone-containing polycyclic group, -SO_2-containing polycyclic group or a carbonate-containing polycyclic group.
    • 形成图案的方法包括以下步骤:通过曝光产生酸,通过使用具有通过酸性行为相对于显影液变化的溶解度的感光性树脂复合体在支撑体上形成感光性树脂膜,使感光性曝光 通过使用含有机溶剂的显影液形成游离图案(1),将曝光的感光性树脂膜显影为负极; 在形成有游离图案的支撑体上涂布表面处理试剂,加热涂布有表面处理试剂的支撑体,形成中和膜(2); 碱性显影形成在支撑体上的自由图案和中和膜,从支撑体去除自由图案,并在支撑体(3)上形成由中和膜形成的图案。 用于形成图案的方法中使用的感光性树脂组合物含有通过酸性行为相对于有机溶剂的溶解性降低的碱成分(A),碱成分(A)含有高分子化合物(A1) 单元(a2-1),含有含内酯的多环基团,含-SO_2的多环基团或含碳酸酯的多环基团。
