Abstract
Methods of forming gate oxide films in integrated circuit devices using wet or dry oxidization processes with a reduced amount of chloride are disclosed. A gate oxide film is formed on a substrate on an active region adjacent to a trench isolation region in a first gas atmosphere with a first amount of chloride. The gate oxide film is annealed in a second gas atmosphere including a second amount of chloride that is greater than the first amount.
