Abstract
A method for fabricating a semiconductor device is disclosed. The method includes forming a first interlayer insulating layer including a first trench that is defined by a first gate spacer and a second trench that is defined by a second gate spacer on a substrate, forming a first gate electrode that fills a part of the first trench and a second gate electrode that fills a part of the second trench, forming a first capping pattern that fills the remainder of the first trench on the first gate electrode, forming a second capping pattern that fills the remainder of the second trench on the second gate electrode, forming a second interlayer insulating layer that covers the first gate spacer and the second gate spacer on the first interlayer insulating layer, forming a third interlayer insulating layer on the second interlayer insulating layer and forming a contact hole that penetrates the third interlayer insulating layer and the second interlayer insulating layer between the first gate electrode and the second gate electrode.
