Abstract:
1. A method for fabricating a capacitor of a semiconductor device, the method comprising the steps of: i) forming an insulating interlayer including a storage node contact hole on a semiconductor substrate; ii) forming a polysilicon layer on the insulating interlayer including the storage node contact hole; iii) forming a sacrificial resist layer on the polysilicon layer, thereby filling the storage node contact hole with the sacrificial resist layer; iv) selectively removing the sacrificial resist layer in such a manner that the sacrificial resist layer remains only in the storage node contact hole; v) implanting ions into the upper surface of an exposed upper surface of the polysilicon layer; vi) oxidizing an ion-implanted portion of the polysilicon layer after removing the remaining sacrificial resist layer; vii) growing an MPS layer on a surface of the polysilicon layer after removing the oxidized portion of the polysilicon layer; and viii) forming a dielectric layer and an upper electrode on the polysilicon layer including the MPS layer.
