    摘要: A protective insulating film is deposited over first and second field-effect transistors formed on a semiconductor substrate. A capacitor composed of a capacitor lower electrode, a capacitor insulating film composed of an insulating metal oxide film, and a capacitor upper electrode is formed on the protective insulating film. A first contact plug formed in the protective insulating film provides a direct connection between the capacitor lower electrode and an impurity diffusion layer of the first field-effect transistor. A second contact plug formed in the protective insulating film provides a direct connection between the capacitor upper electrode and an impurity diffusion layer of the second field-effect transistor.

    摘要: The semiconductor device of the invention includes a capacitor device, which is formed on a substrate and which includes a capacitive lower electrode, a capacitive insulating film made of an insulating metal oxide film and a capacitive upper electrode. An interlevel insulating film having an opening reaching the capacitive upper electrode is formed over the capacitor device. A metal interconnection including a titanium film is formed over the interlevel insulating film so as to be electrically connected to the capacitive upper electrode through the opening. An anti-diffusion film having conductivity is formed between the capacitive upper electrode and the metal interconnection for preventing titanium atoms composing the titanium film of the metal interconnection from passing through the capacitive upper electrode and diffusing into the capacitive insulating film.
