Patent ID: 7560795

Claim:
A device comprising: a first conductor formed over a substrate having a capacitor region and a contact plug region; at least one first insulating layer formed over an entire surface of the substrate including the first conductor; a first contact hole extending through the first insulating layer to expose a first portion of the first conductor over only the capacitor region; a second contact hole extending through the first insulating layer to expose a second portion of the first conductor over only the contact plug region; a second conductor formed in the first contact hole and the second contact hole; a first capacitor insulating layer formed in the first contact hole over the second conductor; a third conductor formed in the first contact hole over the capacitor insulating layer, and having a trench therein; a second capacitor insulating layer formed in the trench; a fourth conductor formed in the trench over the second capacitor insulating layer; and a contact plug formed over the second conductor in the second contact hole, wherein the fourth conductor and the contact plug are electrically coupled to each other.
