    摘要: A resist pattern formation method includes providing a first positive-tone radiation-sensitive resin composition on a substrate to form a first resist layer. The first resist layer is selectively exposed and developed to form a first resist pattern. The first resist pattern is coated with a resist pattern insolubilizing resin composition which comprises a resin and an alcohol solvent, the resin having a hydroxyl group. The resist pattern insolubilizing resin composition is baked or cured with UV to insolubilize the first resist pattern in a developer and in a second positive-tone radiation-sensitive resin composition. The resist pattern insolubilizing resin composition is developed to form an insolubilized resist pattern. The second positive-tone radiation-sensitive resin composition is provided on the insolubilized resist pattern to form a second resist layer. The second resist layer is selectively exposed and developed to form a second resist pattern.

The resin composition for forming a micropattern includes a hydroxyl group-containing resin, a crosslinking component, and an alcohol solvent which contains an alcohol and not more than 10 mass % of water relative to the total solvent. The crosslinking component includes a compound having two or more acryloyloxy groups in the molecule.

    摘要: A resist pattern-forming method includes forming a first resist pattern using a first positive-tone radiation-sensitive resin composition. A resist pattern-miniaturizing resin composition is applied to the first resist pattern. The resist pattern-miniaturizing resin composition applied to the first resist pattern is baked and developed to form a second resist pattern that is miniaturized from the first resist pattern. A resist pattern-insolubilizing resin composition is applied to the second resist pattern. The resist pattern-insolubilizing resin composition applied to the second resist pattern is baked and washed to form a third resist pattern that is insoluble in a developer and a second positive-tone radiation-sensitive resin composition. A second resist layer is formed on the third resist pattern using the second positive-tone radiation-sensitive resin composition. The second resist layer is exposed and developed to form a fourth resist pattern.
