Abstract
In order to supply a semiconductor device having high-reliability, there are used a first capacitor electrode, a capacitor insulating film formed in contact with the first capacitor electrode and mainly composed of titanium oxide, and a second capacitor electrode formed in contact with the capacitor insulating film, and there is used a conductive oxide film mainly composed of ruthenium oxide or iridium oxide for the first capacitor electrode and the second capacitor electrode. Alternatively, there is used a gate insulating film having a titanium silicate film and titanium oxide which suppress leakage current.
