Patent ID: 7247537

Claim:
A method of manufacturing a capacitor comprising: depositing a contact region on a substrate; depositing a mold layer on the substrate; forming an opening at a surface portion of the mold layer that is disposed over the contact region; after forming the opening, forming a connecting member on a sidewall of the opening; exposing the connecting member and the contact region by forming a contact hole through the mold layer; forming a storage conductive layer pattern on sidewalls of the connecting member and the contact hole, the storage conductive layer pattern touching the contact region; removing the mold layer to form a storage electrode that includes the connecting member and the storage conductive layer pattern; depositing a dielectric layer on the storage electrode; and depositing a plate electrode on the dielectric layer, wherein adjacent electrodes are connected to one another by the connecting member, wherein forming the opening comprises: depositing a mask layer on the mold layer; etching the mask layer to form a mask; etching the mold layer using the mask to form a first opening having a first width and a first depth at a surface portion of the mold layer; and extending the first opening to form a second opening having a second width that is greater than the first width and a second depth that is greater than the first depth.
