Abstract: Semiconductor device having less defects in a gate insulating film and improved reliability and methods of forming the semiconductor devices are provided. The semiconductor devices may include a gate insulating film on a substrate and a gate electrode structure on the gate insulating film. The gate electrode structure may include a lower conductive film, a silicon oxide film, and an upper conductive film sequentially stacked on the gate insulating film. The lower conductive film may include a barrier metal layer.
