Its excellent optical properties and electrical properties, making aluminum films in microelectronic circuits, a thin film circuit and the optical thin film is widely used in. At present, the Al thin film research mainly has two aspects: on the one hand ultrathin aluminum films optical and electrical properties; on the other hand the aluminum thin films in the fabrication of multilayer film in rats. This design uses a ron sputtering method to prepare the Aluminum film, and through the work pressure and sputtering temperature control to study the influence of the refractive index of Aluminum, as well as the microstructure of these parametric conditions. Ellipsometry Thickness Gauge to measure the refractive index, using atomic force microscopy and metallographic microscope to observe the surface morphology and particle size of the Aluminum film. From the data analysis of the relationship between working pressure and substrate temperature and plex refractive index and surface morphology of the Aluminum film.
