Abstract
A semiconductor structure includes a semiconductor substrate, a transistor, a plurality of isolation structures, and a conductive feature. The transistor is over the semiconductor substrate. The isolation structures are over the semiconductor substrate. The isolation structures define a semiconductor ring of the semiconductor substrate surrounding the transistor. The conductive feature extends vertically in the semiconductor substrate and surrounds the transistor and semiconductor ring. The conductive feature has a rounded corner facing the semiconductor ring from a top view.
