    摘要: A hydrogen barrier layer is formed above a ferroelectric thin film in an integrated circuit. The hydrogen barrier layer is directly over a protected segment of the ferroelectric thin film, while a sacrificial segment of the ferroelectric thin film extends laterally beyond the edges of the hydrogen barrier layer. The sacrificial segment absorbs hydrogen so that it cannot diffuse laterally into the protected segment of the ferroelectric thin film. After it absorbs hydrogen, the sacrificial segment is etched away to allow electrical connection to circuit layers below it. The ferroelectric thin film preferably comprises a layered superlattice compound. Excess bismuth or niobium added to the standard precursor solution of a strontium bismuth tantalum niobate compound helps to reduce hydrogen degradation of the ferroelectric properties.

    摘要: An integrated circuit is formed that contains a ferroelectric element comprising metal oxide material containing at least two metals. An oxygen-recovery anneal is conducted in ambient oxygen at a temperature range from 300.degree. to 1000.degree. C. for a time period from 20 minutes to 2 hours. The oxygen-recovery anneal reverses the effects of hydrogen degradation and restores ferroelectric properties. The oxygen-recovery anneal is more effective as the annealing temperature and annealing time increase. Preferably the metal oxide element comprises a layered superlattice compound. Hydrogen degradation of the ferroelectric properties is minimized when the layered superlattice compound comprises strontium bismuth tantalum niobate and the niobium/tantalum mole ratio in the precursor is about 0.4. Hydrogen degradation is further minimized when at least one of the superlattice generator-element and the B-site element of the layered superlattice compound is present in excess of the amounts represented by the balanced stoichiometric formula of the compound.
