  • Patent number: 8089153
    Abstract: Method for eliminating loading effect using a via plug. According to an embodiment, the present invention provides a method of processing an integrated circuit wherein a loading effect is reduced. The method includes a step for providing a substrate, which is characterized by a first thickness. The method also includes a stop for forming an inter metal dielectric layer overlaying the substrate. The inter metal dielectric layer is characterized by a second thickness. The method additionally includes a step for forming a first photoresist layer overlaying the inter metal dielectric layer. The first photoresist layer is associated with a first pattern. Additionally, the method includes a step for forming a first opening positioned at least partially inside the inter metal dielectric layer. The first via opening is characterized by a first depth. The method additionally includes a step for removing the first photoresist layer. The method further includes a step for forming a via plug.
