A semiconductor device and a method for manufacturing the same are disclosed. When forming a profile of the lower electrode, a second lower electrode hole (i.e., a bunker region) located at the lowermost part of the lower electrode is buried with an Ultra Low Temperature Oxide (ULTO) material without damaging the lower electrode material. As a result, when a dielectric film is deposited in a subsequent process, the above-mentioned semiconductor device prevents the occurrence of a capacitor leakage current caused by defective gapfilling of the dielectric film located at the lowermost part of the lower electrode. |
