ABSTRACT:
The invention provides a positive-working photosensitive resin composition comprising an alkali soluble resin (A), a diazoquinone compound (B) and a compound (C) which contains a —CH2OH group but not a phenolic hydroxyl group, a method for producing a pattern-formed resin film using the composition, a semiconductor device and a display device using the composition, and a method for producing the semiconductor device and the display device. Also, the present invention provides a positive-working photosensitive resin composition comprising an alkali soluble resin (A), a diazoquinone compound (B) and a mixture solvent of two or more kinds (D), wherein the mixture solvent (D) contains γ-butyrolactone and propylene glycol monoalkyl ether and the total amount of γ-butyrolactone and propylene glycol monoalkyl ether is about 70 wt % or more of the total amount of solvent, a method for producing a pattern-formed resin film using the composition, a semiconductor device and a display device using the composition, and a method for producing the semiconductor device and the display device.
