摘要: Embodiments of the current invention include methods of forming a strontium titanate (SrTiO3) film using atomic layer deposition (ALD). More particularly, the method includes forming a plurality of titanium oxide (TiO2) unit films using ALD and forming a plurality of strontium oxide (SrO) unit films using ALD. The combined thickness of the TiO2 and SrO unit films is less than approximately 5 angstroms. The TiO2 and SrO units films are then annealed to form a strontium titanate layer.
