Abstract
The present disclosure provides a method for fabricating an integrated circuit (IC). The method includes receiving an IC layout having active regions, conductive contact features landing on the active regions, and a conductive via feature to be landing on a first subset of the conductive contact features and to be spaced from a second subset of the conductive contact features; evaluating a spatial parameter of the conductive via feature to the conductive contact features; and modifying the IC layout according to the spatial parameter such that the conductive via feature has a S-curved shape.
