Patent ID: 7094660

Claim:
A method of manufacturing a semiconductor device, the method comprising: forming a contact region at a surface portion of a semiconductor substrate; forming at least one first mold layer on the substrate; forming a first insulation layer on the first mold layer; forming a second mold layer on the first insulation layer; forming a first opening by partially etching the second mold layer, the first insulation layer, and the first mold layer; forming a stabilizing member on an inner sidewall of the first opening, wherein the stabilizing member has a protruding portion to support adjacent storage electrodes; forming a contact hole to expose an inner sidewall of the stabilizing member and the contact region; forming a storage electrode to contact the contact region on the inner sidewall of the stabilizing member and an inner sidewall of the contact hole; forming a dielectric layer on the storage electrode; and forming a plate electrode on the dielectric layer.
