Abstract: A method of fabricating a patterned polymer film with nanometer scale includes filling particles each having a predetermined size in a pattern provided to a soft polymer mold to prepare an embossed stamp; placing the embossed stamp on a desired polymer film; allowing the embossed stamp placed on the polymer film to stand at temperatures higher than a glass transfer temperature of the polymer film for a predetermined time; and releasing the embossed stamp from the polymer film. Alternatively, the patterned polymer film is obtained by filling particles each having a predetermined size in a pattern provided to a soft polymer mold to prepare an embossed stamp; placing the embossed stamp on a coating layer of a polymer precursor formed on a substrate; curing the coating layer; and releasing the embossed stamp from the cured coating layer.

Abstract: A method of preparing patterned colloidal crystals includes filling a monomer solution in the interstices between particles of planar colloidal crystals for photopolymerization inside them, and performing a selective photopolymerization process between the colloidal crystals using a mask.

Abstract: Disclosed herein is a method of preparing silica slurry for wafer polishing. This method includes pre-treating relatively inexpensive and commercially available fumed or colloidal silica particles as a seed by a settling, a crushing using a ball mill and a paint shaker, and a sonication to produce an aqueous dispersion of the silica particles. The pre-treated silica particles are then combined with tetraethylorothosilicate as a precursor, an alcohol solvent and a base, and grown to a desired size by hydrolysis and polycondensation of the precursor, tetraethylorothosilicate. Then, the alcohol solvent, in which the silica particles are grown, are displaced with water by a vacuum distillation. The resulting aqueous dispersion of the grown silica dispersion is hydrothermally treated in an autoclave. Thus, this method allows the economical preparation of the spherical silica particles having a highly uniform size and a very high purity.
