| 摘要 |
A method for manufacturing a semiconductor device includes at least forming a lower electrode made of titanium nitride on a semiconductor substrate, forming a dielectric film comprising zirconium oxide, in which at least the uppermost layer of the dielectric film is formed by an atomic layer deposition (ALD) method on the lower electrode, forming a first protective film on the dielectric film without exceeding the film forming temperature of the ALD method over 70° C., and forming an upper electrode made of a titanium nitride on the first protective film. |
