    摘要: Provided herein are semiconductor devices with through electrodes and methods of fabricating the same. The methods may include providing a semiconductor substrate having top and bottom surfaces facing each other, forming on the top surface of the semiconductor substrate a main via having a hollow cylindrical structure and a metal line connected to the main via, forming an interlayered insulating layer on the top surface of the semiconductor substrate to cover the main via and the metal line, removing a portion of the semiconductor substrate to form a via hole exposing a portion of a bottom surface of the main via, and forming in the via hole a through electrode that is electrically connected to the main via. The bottom surface of the main via is overlapped by a circumference of the via hole, when viewed in a plan view.
