发明名称 Method for manufacturing semiconductor device
摘要 A method for manufacturing a semiconductor device includes forming an oxide film uniformly in a trench in the device isolation by, for example, a radical oxidation process. The method also includes increasing the thickness of the oxide film positioned at recess sidewalls by forming a gate oxide film. Manufacturing the device according to this method will prevent junction leakage and maintain a gate oxidation intensity characteristic that will improve the refresh characteristic of the device.
