Patent ID: 7102186

Claim:
A semiconductor device comprising: a first insulating film formed over a semiconductor substrate; a capacitor lower electrode formed over the first insulating film to have a contact region; capacitor upper electrodes formed over a region of the capacitor lower electrode except the contact region at an interval mutually; a dielectric film formed between the capacitor lower electrode and the capacitor upper electrodes to cover the capacitor lower electrode in an area between the capacitor upper electrodes; an electrically isolated conductive pattern formed around the contact region of the capacitor lower electrode and having a same layer structure as a conductive film constituting the capacitor upper electrodes; wherein the isolated conductive pattern is formed in a region between the capacitor upper electrodes and the contact region of the capacitor lower electrode and has a rectangular shape to extend along the boundary between the dielectric film and the contact region of the capacitor lower electrode, and wherein the dielectric film is formed continuously from an area under the isolated conductive pattern to areas under the capacitor upper electrodes.
