摘要:
A method for forming a capacitor of a semiconductor device includes forming a first insulation layer having a storage node plug on a semiconductor substrate; forming an etch stop layer and a second insulation layer sequentially on the substrate having the first insulation layer; forming a hole exposing a portion of the storage node plug by selectively etching the second insulation layer by using the etch stop layer; recessing a portion of the storage node plug exposed by the hole; forming a barrier metal layer on a surface of the recessed storage node plug; forming a storage node electrode connected to the storage node plug through the barrier metal layer in the hole; and forming a dielectric layer and a metal layer for a plate electrode sequentially on the storage node electrode.
