An integrated circuit device includes a first conductive line and a second conductive line that are spaced apart from each other and extend in a first direction to be parallel to each other; and a contact pad including a pad body including a first branch portion from which the first conductive line branches and a second branch portion from which the second conductive line branches and a loop branch portion that is located between the first branch portion and the second branch portion and protrudes from the pad body. Related devices and fabrication methods are also discussed.
