| Research Abstract |
The purpose of this research is to develop novel thin-film deposition system equipped recycling system for metal-organic precursors, which is designed totally based on supercritical fluid technology. The present research project was accomplished through (i) the trial production of recycling system for metal-organic compounds by extraction and separation process using supercritical carbon dioxide (CO_2), (ii) simulated experiment for collecting metal-organic compounds under pseudo-condition in film-deposition equipment, and (iii) conclusive discussion for simultaneous collection of unreacted precursors and byproduct compounds during film-deposition process under supercritical CO_2. We obtained some valuable data and knowledge for dissolution and decomposition behavior of Ti β-diketonates, typical precursors for titanium dioxide (TiO_2) films, under supercritical CO_2 condition, and then clarified the reaction mechanism from metal-organic precursors to solid TiO_2 deposition.
