Micropattern formation material and method of micropattern formation

The present invention provides a method of forming a fine pattern, comprising the steps of forming a resist pattern 3 made of a chemically amplified photoresist on a substrate 1 with a diameter of 6 inches or more, applying a fine pattern forming material containing a water-soluble resin, a water-soluble crosslinking agent and water or a mixed solvent of water and a water-soluble organic solvent to form a coated layer 4, baking the chemically amplified photo resist pattern and the coated layer, and developing the coated layer after baking, wherein the water-soluble resin in the fine pattern forming material is a water-soluble resin, the peak temperature of heat of fusion of which in a DSC curve is higher than the baking temperature in the above baking step and simultaneously higher than 130°C.
