摘要:
A method for forming a minute pattern mask includes forming an etching target layer on a substrate. A convex pattern including a plurality of convex parts is formed on the etching target layer. A resin composition is coated on the convex pattern to form a resin layer including a first region neighboring the convex part and a second region positioned between the neighboring convex parts. The resin layer is ashed or etched to form the plurality of first resin patterns. The plurality of first resin patterns is processed to form a minute pattern mask including a plurality of second resin patterns. The etching target layer is etched using the plurality of second resin patterns as an etch mask to form a minute pattern.

Disclosed is a method of forming a hierarchical microstructure using partial curing, which is simple in the manufacturing process and capable of forming a hierarchical structure without heterogeneous interfaces. To this end, there is provided a method of forming a hierarchical microstructure using partial curing, including forming a first polymer pattern having partial curing layers and forming a second polymer pattern on the first polymer pattern by using the partial curing layers. According to the present invention, a microstructure having various hierarchical structures can be formed by using a simple process. Accordingly, efficiency in various processes in which a microstructure having various hierarchical structures needs to be formed and economic efficiency can be improved. Furthermore, new functional materials, having not only super hydrophobicity, but also a high adhesive property even in a rough surface, can be developed.

Provided are a dry adhesive fastening system which has a relatively superior adhesion, does not almost generate noises during the attaching or detaching operation, has a simplified structure adapted to mass production requirements, and a method of using the same. For this, the dry adhesive fastening system includes a first adhesion member having a first microvillus disposed on a first board and a second adhesion member having a second microvillus disposed on a second board to contact the first adhesion, thereby providing adhesion. Also, unlike the existing velcro fastening system, the hook and loop may not be classified to improve production yield and effectiveness. Also, during the attachment/detachment, the noises may do not occur. In addition, since the microvillus having the micro or nano size is used, the adhesion may be realized even though a very small area is provided. Therefore, the dry adhesive fastening system according to the embodiment of the present invention may be applied in fields greater than those of the existing velcro fastening system.
