    Abstract: The present invention relates generally to a method of fabricating a flash memory device. The method includes forming a tunnel dielectric layer on a semiconductor substrate using a plasma oxidization process. The tunnel dielectric layer is formed using the plasma oxidation process employing Ar and O2 gases, therefore, defect charges can be prevented from being created due to dangling bonds such as Si—H. Accordingly, the shift of the threshold voltage (Vth) of a device can be reduced and cycling and charge retention characteristics can be improved.
