Popis: | Amorphous carbon nitride (a-CN x ) films made by a reactive sputtering of a carbon target with nitrogen plasma shows high resistivity and high electrical breakdown field. Therefore, a-CN x is a good material as a dielectric material. In this paper, the effects of hydrogen-plasma and oxygen-plasma treatment to the dielectric properties of a-CN x films were studied, discussed and compared. A cyclic process of the deposition of a thin a-CN x film and hydrogen- and oxygen-plasma treatment, which is called the layer-by-layer process (LL), were used to make LLa-CN x and LLa-CN x O y films, respectively. Comparing the results of capacitance made of a-CN x , LLa-CN x , and LLa-CN x O y the most effective treatment to get smaller dielectric constant materials at present was to use hydrogen plasma treatment. |
