Abstract
The present application discloses a semiconductor device and a method for fabricating the semiconductor device. The semiconductor device includes a substrate; a landing pad positioned over the substrate; a top dielectric layer including a flat portion positioned on a top surface of the landing pad, and a cavity portion connecting to the flat portion, surrounding the landing pad in a top-view perspective, recessing toward the substrate in a cross-sectional perspective, and including a U-shaped cross-sectional profile, resulting in a cavity with a broadened opening; and a filling layer positioned on the top dielectric layer and filling the cavity. A width of the cavity and a width of the broadened opening are substantially the same.
