The semiconductor device comprises a semiconductor substrate 10; a capacitor element 40 formed above the semiconductor substrate and including a lower electrode 34, a capacitor insulation film 36 formed on the lower electrode and an upper electrode 38 formed on the capacitor insulation film; a shield layer 14, 58 formed at least either of above and below the capacitor element; and a lead-out interconnection layer 22, 50 formed between the capacitor element and the shield layer and electrically connected to the lower electrode or the upper electrode, a plurality of holes 16, 60 being formed in each of the shield layer and the lead-out interconnection layer. The shield layers are formed above and below the MIM capacitor, whereby combination of noises with the MIM capacitor can be prevented.
