Abstract
A semiconductor device having a capacitor which includes a first electrode electrically coupled to a transistor and a second electrode separate from the first electrode and covered with an interlayer insulating film, in which a plurality of coupling holes are formed in the interlayer insulating film and are in contact with the second electrode at the lower ends; and, when the capacitance of the second electrode is represented by C [nF] and the total area of the lower ends of the coupling holes is represented by A [μm], the following expression (1) is satisfied.≦1.98 [nF/μm]  (1) The elution of the second electrode constituting the capacitor at the lower ends of the coupling holes is suppressed.
