The microscopical composition structure and its relationship to fabricated film process of SiO_xN_y dielectric film in nanometre range formed by low temperature PECVD were analysed with Anger electron spectrum (AES) and Fourier transform infrared spectroscopy (FTIR). The physical and optical properties of the thin film were measured by ellipsometer.

The microscopical composition structure and its relationship to fabricated film process of SiO_xN_y dielectric film in nanometre range formed by low temperature PECVD were analysed with Anger electron spectrum (AES) and Fourier transform infrared spectroscopy (FTIR). The physical and optical properties of the thin film were measured by ellipsometer. The research results show that the distributions of nitrogen, oxygen etc. elements in the dielectric film present uniformaly, the contents of these elements at the interface change strongly. The effects of chamber pressure variations under high and low ranges on film microscopical composition actions are different. The thin film is non-crystal state containing both similar Si_3N_4 and similar SiO_2. and it presents a structure of structureless net. With the increase of nitrogen or oxygen contents, the thin film changes respectively into the film in structure of more Si_3N_4or SiO_2. The nitrogen-rich SiO_xN_y film fabricated by the optimized process condition is improved in property and structure.

测量材料表面氧化膜厚度的方法包括间接法(热重法,通过计算转换为氧化层厚度)和直接法(椭圆偏振光谱法),其中椭圆偏振光谱法国内用的相对较少。本文对椭圆偏振光谱测量技术圆偏振光谱建立模型,并采用这种方法对铀进行研究,测量了其在室温环境,相对湿度为50%~70%条件下的氧化膜厚度变化。结果表明采用椭圆偏振技术对铀的测试结果得到的厚度与时间的关系与国内外报道的文献相似,呈抛物线型。
