    Abstract: Integrated circuit devices may include a fin-type active region extending on a substrate in a first horizontal direction, a gate line extending on the fin-type active region in a second horizontal direction, a source/drain region on the fin-type active region and adjacent to the gate line, and a source/drain contact pattern connected to the source/drain region. The source/drain contact pattern may include a first portion and a second portion, the first portion having a first height, and the second portion having a second height less than the first height. The source/drain contact pattern may include a metal plug in the first and second portions and a conductive barrier film on sidewalls of the metal plug in the first and second portions. A first top surface of the conductive barrier film in the second portion is lower than a top surface of the metal plug in the second portion.

    Abstract: A semiconductor device includes a substrate including active patterns, a device isolation layer filling a trench between a pair of adjacent active patterns, a gate electrode on the active patterns, and a gate contact on the gate electrode. Each active pattern includes source/drain patterns at opposite sides of the gate electrode. The gate contact includes a first portion vertically overlapping with the gate electrode, and a second portion laterally extending from the first portion such that the second portion vertically overlaps with the device isolation layer and does not vertically overlap with the gate electrode. A bottom surface of the second portion is distal to the substrate in relation to a bottom surface of the first portion. The bottom surface of the second portion is distal to the substrate in relation to a top of a source/drain pattern that is adjacent to the second portion.
