Abstract:
1. A semiconductor device comprising: a semiconductor substrate having a circuit forming region and a peripheral region; a base insulating film formed over the semiconductor substrate; a capacitor formed of a lower electrode, a capacitor dielectric film made of a ferroelectric material, and an upper electrode in this order over the base insulating film in the circuit forming region; an uppermost interlayer insulating film formed over the capacitor; a seal ring formed over the semiconductor substrate in the peripheral region, the seal ring having a height that reaches at least an upper surface of the interlayer insulating film, and surrounding the circuit forming region; a block film formed over the seal ring and the interlayer insulating film in the circumference of the seal ring; and an electrode conductor pattern which is formed over the interlayer insulating film in the peripheral region, the electrode conductor pattern having an electrode pad, and having a cross-section exposed to a dicing surface, wherein the block film is separated from the electrode pad.
