Abstract: PURPOSE: A method for fabricating a three-dimensional photonic crystal structure using a spin-coating method is provided to form the three-dimensional photonic crystal structure by using silica balls of nano size. CONSTITUTION: A predetermined pattern is formed on a substrate by using photoresist. An etching process is performed on the substrate by using hydrofluoric acid. The photoresist is removed from the substrate in order to form a projection on the substrate. The substrate is fixed to a spin coater. Silica balls are moved to the outside by the centrifugal force while the colloid solution is dropped onto the substrate. The silica balls are stacked by the projection.

Abstract: PURPOSE: A sol-gel process for preparing silica spheres is provided to obtain silica spheres having a uniform size which is used in constructing three-dimensional crystals, and to improve the reproducibility . CONSTITUTION: The sol-gel process for preparing silica spheres uses an order of adding additives different from the order currently used in conventional sol-gel processes to improve the reproducibility. Particularly, H2O and TEOS(tetraethoxysilane) are preliminarily added to ethanol and then the mixture is stirred for 10 minutes. Finally, NH4OH is added to the resultant mixture. In other words, the order of adding TEOS and NH4OH is reverse compared to conventional sol-gel processes.
