Abstract:
A semiconductor device, comprising in the order recited:a substrate; an MOS transistor formed on the substrate; a first interlayer dielectric provided on at least a portion of the MOS transistor; a hydrogen occluding material which is an interstitial hydrogen occluding material, which is provided on the first interlayer dielectric, and which is employed as a wire by being disposed in the vicinity of the top of the MOS transistor; a second interlayer dielectric provided on the hydrogen occluding material to substantially cover the hydrogen occluding material; and a ferroelectric capacitor which has a height which is greater than that of the MOS transistor, and which is positioned apart from the hydrogen occluding material so that hydrogen released from the hydrogen occluding material is supplied to the MOS transistor but not to the ferroelectric capacitor.
