Patent ID: 6849300

Claim:
A method for forming a high dielectric layer comprising a first metal element, a titanium element and an oxygen element, the method comprising: performing a reaction process to adsorb a first organic source onto a substrate, wherein the first organic source comprises the first metal element to which a ligand is combined, and wherein the ligand comprises a C—H bond and an oxygen; forming an atomic layer of the first metal element and the oxygen element by inducing reduction and oxidation between the first organic source and a NH 3 gas; performing a reaction process to adsorb a second organic source onto the atomic layer, wherein the second organic source includes the titanium element to which a ligand is combined, and wherein the ligand comprises a C—H bond and an oxygen; and forming an atomic layer of the titanium element and the oxygen element by inducing reduction and oxidation between the second organic source and a NH 3 gas.
