Method of fabricating barium strontium titanate

摘要

A precursor liquid comprising barium and strontium 2-ethylhexanoates and titanium 2-methoxyethanol in a 2-methoxyethanol solvent is prepared, a substrate is placed within a vacuum deposition chamber, the precursor liquid is misted, and the mist is flowed into the deposition chamber while maintaining the chamber at ambient temperature to deposit a layer of the precursor liquid on the substrate. The liquid is dried, baked, and annealed to form a thin film of barium strontium titanate on the substrate. Then an integrated circuit is completed to include at least a portion of the layered superlattice material film in a component of the integrated circuit.
