Abstract:
A radiation-sensitive resin composition comprising an alkali-soluble resin and a photosensitizer having a quinonediazide group, wherein the alkali-soluble resin is a novolak resin treated by a thin film distillation method, wherein said novolak resin treated by a film distillation method shows the following ratio in area in its profile in gel permeation chromatography with a detector at 280 nm:B2/B1&gE;0.95, C2/(A2+B2+C2)&gE;0.060 wherein A1 is a high-molecular region, B1 is a middle-molecular region, and C1 is a monomer/dimer region before fractional treatment of the novolak resin, and A2, B2 and C2 are the corresponding counterparts after fractional treatment of the novolak resin.
