    Abstract: An integrated circuit having small layout area and a method of forming the same are provided. A slant contact is formed by shifting a portion of a contact a distance less than a whole dimension of the contact along the direction shifted. By using slant contacts, the optical proximity effect is reduced, the device density in the integrated circuit is increased and cross talk is reduced. In the preferred embodiment, the slant contact is combined with other techniques such as compound interconnection, butted local interconnection and slim spacers to reduce the layout area. In another embodiments, a six-transistor SRAM cell can be designed with a slant contact, compound interconnection and butted local interconnection to reduce the layout area.
