Abstract:
1. A capacitor comprising: a first insulating film formed on a substrate; a contact plug formed within said first insulating film; a first vertical electrode formed above the first insulating film and staggered with respect to the contact plug, the first vertical electrode having a sidewall, the first vertical sidewall being used for an upper electrode of a capacitor; a vertical dielectric film formed on the vertical sidewall of the first vertical electrode; and a second vertical electrode formed on top of the contact plug and formed at one side of the vertical dielectric film so that the vertical dielectric film is sandwiched between the first and second vertical electrodes, the second vertical electrode being used as a lower electrode of the capacitor, wherein a top surface of the second vertical electrode is of the same level as that of the first vertical electrode.
