Abstract

An apparatus for forming a high dielectric oxide film includes a controllable atomic oxygen source and a vaporized precursor source. A deposition chamber for receiving the atomic oxygen from the atomic oxygen source and vaporized precursor from the vaporized precursor source is used for deposition of the high dielectric oxide film on a surface of a structure located therein. The apparatus further includes a detection mechanism for detecting a characteristic of the deposition of the high dielectric oxide film on the surface of the structure. The controllable atomic oxygen source is controlled as a function of the detected characteristic.
