The present invention relates to the field of a semiconductor device having a ferroelectric material capacitor and method of making the same. The semiconductor device includes a capacitor having a triple-level oxygen barrier layer pattern formed by an oxygen barrier metal layer, a material layer formed of a conductive solid solution by compounding the oxygen barrier metal layer and oxygen, and an oxygen barrier metal on an interlayer dielectric with a contact plug. The capacitor also has an electrode and a ferroelectric film electrically contacting to the oxygen barrier layer. Further, a wetting layer is formed between the oxygen barrier layer and the contact plug, and an iridium oxygen layer is formed between the oxygen barrier layer and a capacitor electrode.
