Micro- and Nanostructures are important to use as a building blocks in modern science and technology. Especially, there are many researches for preparation of embossed surfaces using beads like silica or polystyrene with a variety of sizes. However, research on fabrication of substrate with different distance between beads has not been studied yet. So, we easily manufactured substrates whose embossed parts expanded with same interval using hand-made device, ‘Expander’ and PDMS. In this work, we figured out some optimized conditions for making PDMS such as hardening time for imprinting, thickness and ratio of base to agent for expanding well. Each elasticity of PDMS is measured with tensile strength meter. We prepared PDMS templates with random, hexa- and cubic-array, and assembled various sized silica beads. And then, we expanded the PDMS variously and transferred them to 1*1 cm2 glass substrate immediately. Finally, we fabricated the various dimensional embossed substrates.
