Patent ID: 8206894

Claim:
A resist pattern-forming method comprising: forming a first resist pattern using a first positive-tone radiation-sensitive resin composition; applying a resist pattern-miniaturizing resin composition to the first resist pattern; baking the resist pattern-miniaturizing resin composition applied to the first resist pattern to form a layer soluble by a developer in the first resist pattern; developing the resist pattern-miniaturizing resin composition and the first resist pattern by the developer to dissolve the layer and to form a second resist pattern that is miniaturized from the first resist pattern; applying a resist pattern-insolubilizing resin composition to the second resist pattern; baking and washing the resist pattern-insolubilizing resin composition applied to the second resist pattern to form a third resist pattern that is insoluble in a developer and a second positive-tone radiation-sensitive resin composition; forming a second resist layer on the third resist pattern using the second positive-tone radiation-sensitive resin composition; and exposing and developing the second resist layer to form a fourth resist pattern.
