Abstract
Semiconductor devices, and methods for fabricating a semiconductor device, include forming a contact hole penetrating an interlayer insulating layer and exposing a conductor defining a bottom surface of the contact hole, forming a sacrificial layer filling the contact hole, forming a first trench overlapping a part of the contact hole by removing at least a part of the sacrificial layer, forming a spacer filling the first trench, forming a second trench by removing a remainder of the sacrificial layer, and forming a metal electrode filling the contact hole and the second trench using electroless plating.
