Patent ID: 8679988

Claim:
A method of forming a resistive switching memory device, comprising forming a first layer on a substrate wherein the first layer is operable as a bottom electrode of the resistive switching memory device; forming a second layer above the first layer wherein the second layer comprises a metal oxide material deposited by a first ALD process, wherein the first ALD process comprises a first step of applying a metal-containing precursor and a second step of applying a hydrogen-containing plasma; forming a third layer above the second layer wherein the third layer is operable as a switching layer of the resistive switching memory device, wherein the third layer comprises a metal oxide material deposited by a second ALD process, wherein the second ALD process comprises a first step of applying the metal-containing precursor and a second step of applying an oxidant; and forming a fourth layer above the third layer wherein the fourth layer comprises a metal oxide material deposited by a third ALD process, wherein the third ALD process comprises a first step of applying the metal-containing precursor and a second step of applying an oxygen-containing plasma.
