Zusammenfassung:PURPOSE: A semiconductor device is provided to enable an integration of component having ferroelectric or paraelectric material and to prevent barrier layer domain of a plug from unwilling oxidation. CONSTITUTION: A semiconductor device for integrated circuits with a stack cell located in an insulating layer(2) having a plug(1) filled contact hole(8) with a capacitor with a lower electrode(5) turned towards the plug(1), a paraelectric or ferroelectric dielectric(6) and an upper electrode(7). A barrier layer(3) is located between the plug(1) and the lower electrode(5). The layer is surrounded by a silicon nitride collar(4) preventing effective oxidation of barrier layer(3).
