Abstract:
A method of fabricating a storage node of a stacked capacitor of a semiconductor device comprising:forming a contact plug in an insulating layer on a semiconductor substrate;forming a stacked storage node on the contact plug and the insulating layer;forming a barrier metal spacer on sidewalls of the stacked storage node by depositing a metal on the insulating layer and the storage node and etching back the barrier metal to a thickness of about 450 .ANG. to 500 .ANG., the metal being selected from the group consisting of TiAln, TiSiN, TaTiN, and TaAlN;forming a transition metal spacer on the barrier metal spacer; andforming a high dielectric film on the insulating layer, the stacked storage node, and the transition metal spacer.
