Abstract:
A semiconductor device comprising an integrated circuit and a capacitor formed on the integrated circuit, said capacitor comprising a bottom electrode composed of a conductive layer formed on an insulating layer of the integrated circuit, a capacitor dielectric layer composed of one of a ferroelectric layer and a high dielectric layer formed on the bottom electrode, and a top electrode composed of a conductive layer formed on the capacitor dielectric layer, the top electrode and bottom electrode of the capacitor being connected with interconnections of the integrated circuit through contact holes provided in an interlayer insulating layer formed so as to cover the capacitor, and a passivation layer formed to cover the interconnections, said passivation layer comprising a first silicon nitride layer with the hydrogen atom content of 10.sup.21 atoms/cm.sup.3 or less formed by sputtering, said first silicon nitride layer not comprising activated hydrogen, and a second silicon nitride layer formed on the first silicon nitride layer by plasma CVD thereby forming an overlapping portion, wherein the part of said overlapping portion that covers said interconnections has no humidity-resistant hydrogen barrier layer located between the first silicon nitride layer and the second silicon nitride layer.
