Abstract: Various embodiments of the present disclosure are directed towards a trench capacitor with a trench pattern for yield improvement. The trench capacitor is on a substrate and comprises a plurality of capacitor segments. The capacitor segments extend into the substrate according to the trench pattern and are spaced with a pitch on an axis. The plurality of capacitor segments comprises an edge capacitor segment at an edge of the trench capacitor and a center capacitor segment at a center of the trench capacitor. The edge capacitor segment has a greater width than the center capacitor segment and/or the pitch is greater at the edge capacitor segment than at the center capacitor segment. The greater width may facilitate stress absorption and the greater pitch may increase substrate rigidity at the edge of the trench capacitor where thermal expansion stress is greatest, thereby reducing substrate bending and trench burnout for yield improvements.
