    Abstract: Integrated circuit devices and methods of forming the same are provided. The integrated circuit devices may include a first insulating layer and a plurality of metal wires on the first insulating layer. The plurality of metal wires may include a first metal wire including a first upper surface and a first lower surface that faces the first insulating layer and a second metal wire including a second upper surface and a second lower surface that faces the first insulating layer and is coplanar with the first lower surface. The first metal wire may have a first width monotonically decreasing from the first lower surface to the first upper surface, and the second metal wire may have a second width monotonically increasing from the second lower surface to the second upper surface.

    Abstract: Integrated circuit devices including a metal resistor and methods of forming the same are provided. The integrated circuit devices may include a substrate including a first surface and a second surface that is opposite the first surface and is parallel to the first surface, a transistor including a gate electrode, first and second resistor contacts that are spaced apart from each other in a horizontal direction that is parallel to the second surface of the substrate, and a metal resistor. The first surface of the substrate may face the gate electrode. The metal resistor may include a third surface and a fourth surface that is parallel to the third surface and the second surface of the substrate, and the fourth surface of the metal resistor may be closer to the second surface than the first surface and contacts the first and second resistor contacts.
