Outline of Final Research Achievements

The combined effect of O2 and N2 plasma to the excimer-laser irradiation process was examined. Metal-organic precursor films were irradiated by the laser in O2 plasma, the films were crystalized to the metal-oxide with less oxygen vacancies than those prepared by the laser-irradiation in air. Then, the metal-organic precursor films were irradiated by the laser in N2 plasma, the films were also crystalized to the metal-oxide but included N. Metal films were irradiated by the laser in N2 plasma, especially in the case of Ti, N atoms were introduced into in Ti lattice. The introduction behaviors of N2 depended on the type of metal and it was concluded that the temperature of the film under laser irradiation and the melting point of the metal are dominant factor for introduction of N2.

Academic Significance and Societal Importance of the Research Achievements

窒化物の作製や酸化物相への窒素導入は、一般的には、窒素雰囲気中もしくはアンモニア雰囲気中で、比較的高い熱処理プロセスを必要とする。そのため、窒化物もしくは酸化物相へ窒素導入する場合、周辺材料や下地材料の熱耐性を考慮する必要がある。エキシマレーザ照射法に窒素プラズマを融合したプロセスは、低温で窒素を導入することが可能であるため、窒素含有材料の応用範囲の拡大につながる。
