  • Methods of forming wiring structures
    Patent number: 8298911
    Abstract: In a method of forming a wiring structure, a first insulation layer is formed on a substrate, the first insulation layer comprising a group of hydrocarbon (C?H?) wherein ? and ? are integers. A second insulation layer is formed on the first insulation layer, the second insulation layer being avoid of the group of hydrocarbon. A first opening is formed through the first and the second insulation layers by etching the first and the second insulation layers.
