Abstract:
A pattern forming method includes: (a) forming a first film on a substrate using an actinic ray-sensitive or radiation-sensitive resin composition (I) containing a resin of which solubility in a developer containing an organic solvent decreases due to polarity increased by an action of an acid; (b) exposing the first film; (c) developing the exposed first film using a developer containing an organic solvent to form a first negative pattern; (e) forming a second film on the substrate using an actinic ray-sensitive or radiation-sensitive resin composition (II) containing a resin of which solubility in a developer containing an organic solvent decreases due to polarity increased by an action of an acid; (f) exposing the second film; and (g) developing the exposed second film using a developer containing an organic solvent to form a second negative pattern in this order.

Abstract:
PROBLEM TO BE SOLVED: To provide a photosensitive resin composition capable of producing a heat resistant relief structure, having high sensitivity, ensuring small reduction in film thickness, and excellent in film thickness uniformity in a wafer after development and in film thickness uniformity after curing, and a method for manufacturing a semiconductor device using the composition. SOLUTION: The photosensitive resin composition is characterized by containing a polybenzoxazole precursor having a naphthoquinonediazido group, a naphthoquinonediazide photosensitizer, and a specific compound containing phenolic hydroxyl groups. The method for manufacturing a semiconductor device using the composition is also provided. COPYRIGHT: (C)2007,JPO&INPIT
