摘要： A semiconductor device is produced by fabricating a capacitor element including a lower electrode, a capacitor insulating film, and an upper electrode, and a thin-film resistor element, in the same step. As the lower electrode of the capacitor element is lined with a lower layer wiring layer (Cu wiring), the lower electrode has extremely low resistance substantially. As such, even if the film thickness of the lower electrode becomes thinner, parasitic resistance does not increased. The resistor element is formed to have the same film thickness as that of the lower electrode of the capacitor element. Since the film thickness of the lower electrode is thin, it works as a resistor having high resistance. In the top layer of the passive element, a passive element cap insulating film is provided, which works as an etching stop layer when etching a contact of the upper electrode of the capacitor element.
