摘要

A manufacturing method for an actinic ray-sensitive or radiation-sensitive resin composition that contains a resin, an acid generator, an organic acid, and a solvent, includes at least one of (i), (ii), or (iii) below, and a content ratio of the organic acid in the actinic ray-sensitive or radiation-sensitive resin composition is greater than 5% by mass based on a total solid content in the composition; (i) dissolving the organic acid in a solution that does not substantially contain the resin and the acid generator, (ii) dissolving the organic acid in a solution that contains the acid generator and does not substantially contain the resin, and (iii) dissolving the organic acid in a solution that contains the resin and does not substantially contain the acid generator, an actinic ray-sensitive or radiation-sensitive resin composition, an actinic ray-sensitive or radiation-sensitive film, a mask blank including the film, a forming method for a photo mask and a pattern, a manufacturing method for an electronic device, and an electronic device.
