Title:
METHOD FOR FORMING RESIST PATTERN BY NANOIMPRINT LITHOGRAPHY
Document Type and Number:
Japanese Patent JP2007329276
Kind Code:
A
Abstract:
To provide a method capable of forming a resist pattern at a high aspect ratio having an excellent etching resistance by using a nanoimprint lithography.
The method for forming the resist pattern by the nanoimprint lithography contains a process for forming an organic layer 4 on a supporter 1, and the process for forming a resist layer 2 by using a chemical-amplifying negative resist composition comprising a silsesquioxane resin (A) on the organic layer 4. The method further contains the process for pushing a light transmission type mold 3 partially having a light shield 5 against the resist layer 2, and exposing the resist layer 2 from the mold 3, and the process for peeling the mold 3.
