Bowl-shaped structure, method for manufacturing same, and bowl array

A preparing method of bowl-typed structures, comprising:

• forming an alignment layer of particles on a first substrate by applying physical pressure on the particles, so that the particles align with a regularly spaced distance from each other;
• contacting the alignment layer of particles formed on the first substrate with a second substrate having an adhesive layer formed thereon to transfer the alignment layer of the particles aligned with a regularly spaced distance from each other to the second substrate by adhesion of the adhesive layer;
• coating the alignment layer of the particles transferred onto the second substrate having the adhesive layer with a film-forming material so as to fill a space defining the regularly spaced distance between the particles to form a particle film composite;
• removing the entire adhesive layer and a portion of the film-forming material from the particle film composite to expose the particles and then removing the exposed particles to form a template including holes that are separated by the regularly spaced distance;
• and
• coating the surface of the holes of the template with a first material and then removing the template to form the bowl-typed structures that are separated by the regularly spaced distance.
