Patent ID: 7749856

Claim:
A method of fabricating a storage node with a supported structure, comprising the steps of: providing a substrate having a conductive block therein; forming a stacked structure on the substrate, the stacked structure comprising at least a first dielectric layer on the substrate, a supporting layer on the first dielectric layer and a second dielectric layer on the supporting layer; forming an opening in the stack structure to expose a portion of the conductive block; forming a storage node layer on sidewall of the opening and covering the exposed conductive block; removing the second dielectric layer to expose the supporting layer; conformally forming a spacer layer on the supporting layer and on the storage node layer; selectively removing a portion of the spacer layer to expose portions of the supporting layer; removing portions of the supporting layer to expose portions of the first dielectric layer; and completely removing the first dielectric layer and rest of the spacer layer such that the storage node with a supported structure is formed.
