本文首次采用了金属膜的表面特征来研究金属膜的闪烁噪声。结果表明在二氧化硅和蓝宝石衬底上溅射的铜膜的表面特征及噪声行为都很不相同。粗糙不规则的表面对金属薄膜的闪烁噪声起重要作用。这种噪声的物理模型与MOS器件闪烁噪声的机构类似。
The flicker noise of metal films prepared by sputtering of copper onto the oxidized silicon and sapphire substrates is studied by means of surface characteristics for the first time. The results show that the noise behaviour and the surface physics of the metal films on these two kinds of substrates are different from each other and that the roughness and irregularity of the film surface play an important role in generating the flicker noise of metal film. In addition
the physical model of the noise is similar to the flicker noise mechanism of MOS device.
