Method of manufacturing a capacitor in a semiconductor device |
摘要 |
A method of manufacturing a capacitor in a semiconductor device wherein a first a Ru film used as a lower electrode is deposited by an LPCVD method, a mixed plasma process of Ar and H2 is performed, and a second Ru film is deposited by an LPCVD method, thus improving the surface roughness of the Ru film. The method can obtain a high capacitance and a low leakage current in a capacitor using a Ta2O5 film as a dielectric film.
