Abstract

A method for forming a silicon oxide film includes disposing a silicon oxide film on a surface of a target substrate, and performing a reformation process on the silicon oxide film. The reformation process is performed by annealing the silicon oxide film while exposing the silicon oxide film to oxygen radicals and hydroxyl group radicals.
