However, when the mold is peeled off from the cured product having a low releasability, the precision of the fine pattern of the cured product tends to be lowered. As a method for improving the releasability, a method of applying a release agent to the fine pattern surface of the mold has been proposed. However, the fine pattern accuracy of the mold tends to be lowered due to uneven thickness of the applied release agent. Furthermore, when the mold is used continuously, it is necessary to re-apply the release agent, which tends to reduce the production efficiency.

OMPa (absolute pressure). The mold and the quartz substrate were brought to a temperature of 30 ° C or less and the mold was peeled off.
- a quartz substrate, a polymer (11) layer, and a polymer (21) layer consisted of a fine pattern (height lOOnm X width 0. convex structure on the outermost surface of the polymer (21).
- a mold having a concavo-convex structure arranged at intervals of force 9.) was obtained.
- Example 4 The same ethanol solution and quartz substrate as in Example 4 were prepared, and a quartz substrate subjected to the same surface treatment was obtained.
- the composition 1 obtained in Example 2 was applied to the surface-treated surface of the quartz substrate using a spin coating method, and dried by heating at 180 ° C. for 1 hour.
- the composition 2 obtained in Example 3 was applied onto the surface using a spin coating method and dried by heating at 180 ° C. for 1 hour to form a thin film (thickness 1.3 / zm) made of the polymer (21). ) was obtained.
- the same silicon mold as in Example 4 was heated to 120 ° C., and then pressed onto the thin film side of the quartz substrate at a pressure of 2. OMPa (absolute pressure) for 10 minutes.
- OMPa absolute pressure
- a formed quartz substrate was obtained.
- CF CFCF C (CF) (OCH OCH) in a clean room with UV light cut
- Photocuring initiator 1 (Ciba 'Specialty' Chemicals: Irgacure 651) 0.03 g and 0.03 g of photocuring initiator 2 (manufactured by Ciba 'Specialty' Chemicals: Irgacure 907) were sequentially mixed to obtain a photocurable resin.
- the mold of the present invention is useful as a mold for nanoimprinting using a photocurable resin.
- the treated substrate obtained using the mold of the present invention has a fine pattern on the surface and is useful for various applications.
- the treated substrate is an optical element (microlens array, optical waveguide, optical switching, Fresnel zone plate, binary optical element, blaze optical element, photo-tus crystal, etc.), antireflection filter, biochip, microreactor.
- One chip, a recording medium, a display material, a catalyst carrier and the like can be mentioned.
- the specifications and claims of Japanese Patent Application No. 2004-346029 filed on November 30, 2004 and Japanese Patent Application No. 2005-247722 filed on August 29, 2005, And the entire contents of the abstract are hereby incorporated by reference as the disclosure of the specification of the present invention.
