Research Abstract

1.An electron cyclotron plasma-enhanced chemical vapor deposition apparatus, which is suitable for producing planar fluoride glass films, was developed.
2.ZnFィイD22ィエD2-BaFィイD22ィエD2 thin films were prepared on CaF2(111) substrates by an ECR plasma-enhanced CVD technique. As starting materials of Zn and Ba, β-diketonates of Zn(thd)ィイD22ィエD2 and Ba(hfa)ィイD22ィエD2(tg) were used, respectively. On the other hand, Ar and NFィイD23ィエD2 gases were used as a carrier gas and a fluorinating gas, respectively. ZnFィイD22ィエD2-BaFィイD22ィエD2 thin films were deposited on substrates of single crystal CaFィイD22ィエD2(111) plates under various deposition conditions (plasma power, deposition rate, substrate temperature, etc.) Amorphous thin films were obtained in compositions of ZnFィイD22ィエD2 alone and 60ZnFィイD22ィエD2・40BaFィイD22ィエD2. The synthesis of an amorphous ZnFィイD22ィエD2 film is the first time.
3.For the AlFィイD23ィエD2-BaFィイD22ィエD2 system the preparation of amorphous thins films were attempted using b-diketonates of … More Al(aa)ィイD23ィエD2 and Ba(tfa)ィイD22ィエD2(tg) as starting materials under various CVD conditions. As a result, amorphous thin films were obtained in compositions of AlFィイD23ィエD2 alone, 80AlFィイD23ィエD2・20BaFィイD22ィエD2 and 60AlFィイD23ィエD2・4BaFィイD22ィエD2. The synthesis of an amorphous AlFィイD23ィエD2 film also is the first time.
4.For the GaFィイD23ィエD2-BaFィイD22ィエD2 system the preparation of amorphous thin films were attempted using b-diketonates of Ga(aa)ィイD23ィエD2 and Ba(tfa)ィイD22ィエD2(tg) as starting materials under various CVD conditions. As a result, amorphous thin films were obtained in compositions of GaFィイD23ィエD2 alone and 50GaFィイD23ィエD2・50BaFィイD22ィエD2. The synthesis of an amorphous GaFィイD23ィエD2 film also is the first time.
5.The amorphous thin films synthesizedin the ZnFィイD22ィエD2-BaFィイD22ィエD2, AlFィイD23ィエD2-BaFィイD22ィエD2 and GaFィイD23ィエD2-BaFィイD22ィエD2 systems were characterized by means of thin-film X-ray diffraction, IR absorption, atomic force microscope, thickness and refractive index.
6.It was proved that the developed ECR plasma-enhanced CVD technique is applicable in preparing amorphous thin films of fluoride systems. Less
