Semiconductor device having capacitor which assures sufficient capacity without requiring large space and method of producing the same

摘要

In a semiconductor device comprising first and second layer wirings formed with a space left therebetween and a capacitor formed in the space and electrically connected to the first and the second layer wirings, the capacitor comprises a via electrically connected to one of the first and the second layer wirings, an electrode made of a conductive material and electrically connected to the one of the first and the second layer wirings through the via, and a dielectric film formed between the electrode and the other of the first and the second layer wirings.
