Beschreibung
Zusammenfassung:	A chemically amplified positive-type photosensitive resin composition that can be well developed with an aqueous basic solution having low pH, a substrate with a photosensitive film formed from the composition, and a method for patterned resist film formation using the composition. The composition includes an acid generator that produces an acid upon irradiation with an active ray or radiation; a resin whose solubility in alkali increases under the action of acid; and an organic solvent, in which a predetermined amount of an alkali-soluble resin soluble in an aqueous basic solution having a pH of 12 and containing alkali-soluble groups with hydrogen atoms in at least a part thereof is substituted with an acid-dissociative dissolution-controlling group contained in the resin.
