    摘要: A circuit layout structure includes a wafer having at least a cell region and a scribe line region defined thereon, a metal pattern formed in a first insulating layer in the scribe line region, a second insulating layer and a hard mask layer formed on the metal pattern and the first insulating layer, and at least a dummy pattern formed in the second insulating layer and the hard mask layer in the scribe line region. The dummy pattern has a transmission rate between 0% and 1%.

    摘要: A method for forming a dual damascene structure is disclosed. First a substrate is provided. There are an etching stop layer and an interlayer dielectric layer disposed on the substrate in order. The interlayer dielectric layer has a thickness A. Second, the interlayer dielectric layer is patterned to form a first opening. Later, a photo resist layer with a thickness B is formed on the interlayer dielectric layer. Then, the photo resist layer is patterned by a light source to construct a patterned photo resist layer. Later, the interlayer dielectric layer is again patterned by the patterned photo resist to pattern the interlayer dielectric layer to construct a second opening on the first opening by means of a light source and the photo resist layer so as to form a dual damascene structure. The light source has a periodic parameter C so that (A+B)/C≈X/2, where X is an odd number.
