Resistive switching nonvolatile memory elements are provided. A metal-containing layer and an oxide layer for a memory element can be heated using rapid thermal annealing techniques. During heating, the oxide layer may decompose and react with the metal-containing layer. Oxygen from the decomposing oxide layer may form a metal oxide with metal from the metal-containing layer. The resulting metal oxide may exhibit resistive switching for the resistive switching memory elements.

摘要:
This disclosure provides (a) methods of making an oxide layer (e.g., a dielectric layer) based on yttrium and titanium, to have a high dielectric constant and low leakage characteristic and (b) related devices and structures. An oxide layer having both yttrium and titanium may be fabricated either as an amorphous oxide or as an alternating series of monolayers. In several embodiments, the oxide is characterized by a yttrium contribution to total metal that is specifically controlled. The oxide layer can be produced as the result of a reactive process, if desired, via either a PVD process or, alternatively, via an atomic layer deposition process that employs specific precursor materials to allow for a common process temperature window for both titanium and yttrium reactions.
