Abstract

The invention belongs to the technical field of aluminum film preparation and discloses a method for preparing nano aluminum film by radio frequency magnetron sputtering. The method comprises the following steps: preparing an aluminum film by adopting a way of radio frequency sputtering by using a magnetron sputtering coating machine by taking an aluminum target as a sputtering target and a microscopic glass slide as a substrate; putting the substrate which is washed for 20min with absolute ethyl alcohol into a vacuum cabin, and erasing the substrate dry and putting the same onto a sample table capable of rotating; adjusting the target-substrate distance to 100mm, carrying out vacuumizing, wherein the back bottom vacuum degree of a sputtering apparatus reaches 5.0*10<-4>Pa, introducing argon, the purity of which is 99.99%, setting the argon flow at 40sccm and the temperature at the room temperature and the sputtering time at 600s; and adjusting three process parameters: negative bias,radio-frequency power and working air pressure, and discussing influence of the three process parameters on the depositing rate of the film by means of an orthogonal test. By selecting the process parameters, the aluminum film which is relatively high in depositing rate, good in film quality, relatively great in thickness and fine in grain size is designed.
