    摘要: System and method for reducing contact resistance and improving barrier properties is provided. An embodiment comprises a dielectric layer and contacts extending through the dielectric layer to connect to conductive regions. A contact barrier layer is formed between the conductive regions and the contacts by electroless plating the conductive regions after openings have been formed through the dielectric layer for the contact. The contact barrier layer is then treated to fill the grain boundary of the contact barrier layer, thereby improving the contact resistance. In another embodiment, the contact barrier layer is formed on the conductive regions by electroless plating prior to the formation of the dielectric layer.

    摘要: A method for forming a semiconductor structure includes forming a sacrificial layer over a substrate. A first dielectric layer is formed over the sacrificial layer. A plurality of conductive structures are formed within the sacrificial layer and the first dielectric layer. The sacrificial layer is treated through the first dielectric layer, at least partially removing the sacrificial layer and forming at least one air gap between two of the conductive structures. A surface of the first dielectric layer is treated, forming a second dielectric layer over the first dielectric layer, after the formation of the air gap. A third dielectric layer is formed over the second dielectric layer. At least one opening is formed within the third dielectric layer such that the second dielectric layer substantially protects the first dielectric layer from damage by the step of forming the opening.

    摘要: A method of fabricating a semiconductor device includes forming a via in a dielectric layer that opens to a conductive line underlying the dielectric layer, and forming a via recess in the conductive line at the via. The via recess in the conductive line has a depth ranging from about 100 angstroms to about 600 angstroms. Via-fill material fills the via recess and at least partially fills the via, such that the via-fill material is electrically connected to the conductive line. The via recess may have a same size or smaller cross-section area than that of the via, for example. Such via structure may be part of a dual damascene structure in an intermetal dielectric structure, for example.
