Claim 15:
16. A semiconductor device, comprising:
a substrate including an active region;
a device isolation layer defining active patterns on the active region, the device isolation layer covering a lower side surface of each of the active patterns, an upper portion of each of the active patterns protruding above the device isolation layer;
a pair of source/drain patterns in the upper portion of each of the active patterns;
a channel pattern between the pair of source/drain patterns;
a gate electrode crossing the channel pattern and extending in a first direction;
gate spacers at both sides of the gate electrode and extending in the first direction, along with the gate electrode;
a gate dielectric pattern between the gate electrode and the channel pattern and between the gate electrode and the gate spacer;
a gate capping pattern on a top surface of the gate electrode and extending in the first direction, along with the gate electrode;
a first interlayer insulating layer on the gate capping pattern;
an active contact penetrating the first interlayer insulating layer and being coupled to at least one of the source/drain patterns;
a gate contact penetrating the first interlayer insulating layer and being coupled to the gate electrode;
a first metal-containing layer in a second interlayer insulating layer on the first interlayer insulating layer; and
a second metal-containing layer in a third interlayer insulating layer on the second interlayer insulating layer,
wherein:
the first metal-containing layer includes a lower interconnection line,
the second metal-containing layer includes:
a resistor on the first metal-containing layer;
an upper interconnection line on the resistor; and
a first via below the upper interconnection line and connected to the resistor,

the resistor includes:
a first insulating layer;
a resistor metal layer on the first insulating layer; and
a second insulating layer on the resistor metal layer, and

the resistor metal layer includes a curved concave recessed side surface such that a center portion of the side surface of the resistor metal layer extends along a curve and further inwardly in the resistor metal layer than a top portion of the side surface of the resistor metal layer and extends along a curve and further inwardly in the resistor metal layer than a bottom portion of the side surface of the resistor metal layer.
