A method for manufacturing a semiconductor device improves hot carrier characteristic in a device having a thick gate insulating film without being affected by short channel effect, thereby improving reliability of the device. The method for manufacturing a semiconductor device includes the steps of forming gate electrodes having gate insulating films of different thicknesses on a semiconductor substrate, implanting a low-concentration impurity ion into the semiconductor substrate at both sides of the gate electrodes, implanting a nitrogen ion into a portion, where the low-concentration impurity ion is implanted, in the gate insulating film relatively thicker than the other gate insulating film, forming sidewall spacers at both sides of the gate electrodes, and implanting a high-concentration source/drain impurity ion into the semiconductor substrate.
