Abstract: PURPOSE: A method for fabricating a semiconductor device is provided to prevent a drop in the characteristics of the device due to a hot carrier effect. CONSTITUTION: A semiconductor substrate(30) is first covered with a buffer oxide, and then a resist pattern for exposing a region defined as a gate is formed on the buffer oxide. Next, nitrogen ions are implanted into the substrate(30), so that a buried layer of the nitrogen ions is formed in the substrate(30) under an opening of the resist pattern. After that, the resist pattern and the buffer oxide are wholly removed, and the substrate(30) is subjected to a thermal oxidation. Thus, a gate oxide layer(330) is grown on a surface of the substrate(30). Here, a part of the gate oxide layer(330) above the nitrogen-buried layer is relatively thinner than the other parts. Further, a nitrogen oxide layer(340) is formed on the gate oxide layer(330). Therefore, a hot carrier effect in a drain is reduced by relatively thicker parts of both oxide layers(330,340). Next, to form a gate, conductive layers(35,36) and insulating layers(37,38,39) are successively formed on the oxide layers(330,340) and then patterned.
