A method for fabricating a dielectric layer doped with nitrogen is provided according to the present invention. According to the method, a dielectric layer is formed on a semiconductor substrate. Two steps of nitridation processes are then performed on the dielectric layer. Following that, one step or two steps of annealing processes are performed on the dielectric layer. Dielectric layer formed by the method has uniform nitrogen dopant, and thus has fine electric properties.
