Abstract: A trench capacitor includes an electrode having a first conductive area formed in a trench provided in a substrate, and a second conductive area extending from a bottom of the trench, the second conductive area being electrically coupled to the first conductive area and spaced apart from the first conductive area; a storage node having a first conductive extension extending into a first dielectric space provided between the first conductive area and the second conductive area of the electrode, and a second conductive extension extending into a second dielectric space provided within the second conductive area of the electrode; and a dielectric layer electrically insulating the electrode from the storage node.
