Abstract
An integrated circuit device includes a semiconductor substrate having a first surface and a second surface opposite to the first surface, a first insulating layer on the first surface of the semiconductor substrate, an electrode landing pad positioned on the first surface of the semiconductor substrate and having a sidewall surrounded by the first insulating layer, a top surface apart from the first surface of the semiconductor substrate, and a bottom surface opposite to the top surface, and a through-electrode configured to penetrate through the semiconductor substrate and contact the top surface of the electrode landing pad, wherein a horizontal width of the top surface of the electrode landing pad is less than a horizontal width of the bottom surface of the electrode landing pad and greater than a horizontal width of a bottom surface of the through-electrode in contact with the top surface of the electrode landing pad.
