Abstract
A trench capacitor includes a trench disposed in a substrate; an inner electrode disposed in a central portion of the trench and having a top surface and a bottom surface; an outer electrode disposed symmetrically with respect to the inner electrode, the outer electrode having a depth shallower than a depth of the inner electrode with respect to a top surface of the substrate; a thick bottom insulating layer disposed below the inner electrode and the outer electrode; and a capacitor dielectric layer surrounding the outer electrode. The outer electrode protrudes above the top surface of the substrate and has a top surface that is higher than the top surface of the inner electrode.
