| Zusammenfassung: | The present invention provides a technology capable of providing a semiconductor device having an MIM structure capacitor with improved reliability. The capacitor has a lower electrode, a capacitor insulating film, and an upper electrode. The lower electrode is comprised of a metal film embedded in an electrode groove formed in an insulating film over the main surface of a semiconductor substrate; and the upper electrode is comprised of a film stack of a TiN film (lower metal film) and a Ti film (cap metal film) formed over the TiN film (lower metal film). |
