Abstract: Aluminum Oxide (Al2O3) barrier films were prepared by plasma enhanced atomic layer deposition (PEALD) at 80℃ with flexible polyethylene terephthalate (PET) as substrate. The test results of X-ray photoelectron spectroscopy and ellipsometer show that the prepared Al2O3 films have high purity and good uniformity. Besides, Al2O3 films with different thickness were prepared by adjusting the deposition cycle. The effects of film thickness on surface morphology, surface roughness, optical transmission and water vapor transmittance rate (WVTR) were studied. The results show that Al2O3 film prepared with 500 deposition cycles exhibits the best performance, with a surface roughness of 1.52nm, an average transmittance (400-1200nm) of 90.4%, and a WVTR of 3.15×10-3g·m-2·d-1.

Key words: Al2O3, barrier film, PEALD
