Research Abstract

We have succeeded in fabricating micropatterned TiOィイD22ィエD2 films on self-assembled monolayers (SAM) of phenyltrichlorosilane (PTCS) through the precipitation from an aqueous solution containing TiFィイD26ィエD2ィイD12-ィエD1 ions. A PTCS monolayers was first formed on a silicon water and UV light was irradiated onto the masked monolayer to obtain the SAM with two-dimensionally patterned hydrophilic/hydrophobic surfaces. This patterned substrate was immersed in an aqueous solution to directly deposit TiOィイD22ィエD2 (anatase). Sonication treatment after the deposition resulted in a micropatterned TiOィイD22ィエD2 thin film.
We also succeeded in fabricating micropatterns of titanium dioxide thin films on SAMs. SAMs of OTS (octadecyltrichloro-silane) were formed on Si wafers, and were modified by UV irradiation using a photomask to generate methyl/silanol-pattern. They were used as templates to deposit titanium dioxide thin films by the use of TDD (titanium dichloride diethoxide). Amorphous films with approximate compositions Ti : O : Cl : C = 1 : 2.2 : 0.17 : 0.37 were selectively deposited on silanol regions. Line width variation of the pattern of an as-deposited film was improved to be well below the electronics design rule, 5%.
Novel processes to arrange fine silica spheres two-dimensionally on SAMs were developed. SiOィイD22ィエD2 sphere surfaces were modified to have CN groups by the use of trichlorocyanoethysilane, and CN groups were oxidized to COOH groups with t-BuOK. A SAM of PTCS with a phenyl/silanol-group pattern was used as a template to arrange fine SiOィイD22ィエD2 spheres. SiOィイD22ィエD2 spheres were selectively attached to silanol surfaces possibly forming ester bonds, which enabled the fabrication of micropatterned arrangement of SiOィイD22ィエD2 spheres.
