Abstract
A resistive memory device having an in-situ nitride initiation layer is disclosed. The nitride initiation layer is formed above the first electrode, and the metal oxide switching layer is formed above the nitride initiation layer to prevent oxidation of the first electrode. The nitride initiation layer may be a metal nitride layer that is formed by atomic layer deposition in the same chamber in which the metal oxide switching layer is formed. The nitride initiation layer and metal oxide switching layer may alternatively be formed in a chemical vapor deposition (CVD) chamber or a physical vapor deposition (PVD) chamber.
