  • Patent number: 11450554
    Abstract: To manufacture an integrated circuit (IC) device, a lower structure having a step structure defining a trench is prepared. A material film is formed inside the trench. To form a material film, a first precursor including a first central element and a first ligand having a first size is supplied onto a lower structure to form a first chemisorbed layer of the first precursor on the lower structure. A second precursor including a second central element and a second ligand having a second size less than the first size is supplied onto a resultant structure including the first chemisorbed layer to form a second chemisorbed layer of the second precursor on the lower structure. A reactive gas is supplied to the first chemisorbed layer and the second chemisorbed layer.

  • Patent number: 10347527
    Abstract: A semiconductor device includes a substrate, a first metal interconnection provided on a first region of the substrate, and a second metal interconnection provided on a second region of the substrate. A width of the second metal interconnection is greater than a width of the first metal interconnection. The first metal interconnection includes a metal pattern. The second metal interconnection includes a lower metal pattern having a concave surface at its top, an upper metal pattern disposed on the concave surface at the top of the lower metal pattern, and a first barrier pattern interposed between the lower metal pattern and the upper metal pattern. The metal interconnections are formed by a damascene process including deposition, reflow, metal implantation, and planarization processes.
