Abstract
The method for depositing a dielectric layer can be used to evenly deposit the dielectric layer to be applied to a semiconductor device. The method includes steps of: a) providing a substrate; b) depositing a first dielectric film on the subtrate; c) introducing an oxygen plasma for eliminating an uneven distribution of charges on a surface of the substrate; and d) forming a second dielectric film on the first dielectric film treated with the oxygen plasma for obtaining the dielectric layer having a uniform thickness on the substrate,
