    摘要: A resist pattern coating agent includes a hydroxyl group-containing resin and a solvent. The solvent includes an alcohol shown by a following formula (1) in an amount of about 30 mass % or more, R—OH  (1) wherein R represents a branched alkyl group having 3 to 10 carbon atoms. The resist pattern coating agent is used in a resist pattern-forming method. The method includes forming a first resist pattern on a substrate using a first radiation-sensitive resin composition. The first resist pattern is treated with the resist pattern coating agent. A second resist pattern is formed on the substrate treated with the resist pattern coating agent using a second radiation-sensitive resin composition.

    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.
