Abstract: PURPOSE: A MOS transistor having an anti-oxidizing spacer is provided to minimize a gate bird's beak phenomenon, reduce a threshold voltage, and increase the driving current by forming an anti-oxidizing spacer at a sidewall of a gate electrode. CONSTITUTION: A gate insulating layer(205) is formed on a substrate(200). A gate electrode(210a) is formed on a predetermined region of the gate insulating layer. An anti-oxidizing spacer(215a) is formed on a sidewall of the gate electrode. A source and drain(240) is formed on the substrate of both sides of gate patterns which are formed with the gate electrode and the anti-oxidizing spacer. A gate spacer(235a) is formed at an outer sidewall of the anti-oxidizing spacer. A buffer layer(230) is inserted between the gate spacer and the anti-oxidizing spacer. The anti-oxidizing spacer is formed with one selected from a silicon nitride layer, an aluminum oxide layer, and a tantalum pentaoxide layer.
