    Abstract: A method of forming a dual damascene structure comprises the steps of providing a substrate having a first conductive layer formed thereon, and then sequentially forming a first dielectric layer, an anti-reflection layer and a second dielectric layer over the substrate. Next, the first dielectric layer, the anti-reflection layer and the second dielectric layer are patterned to form a first opening that exposes the conductive layer. Thereafter, the second dielectric layer is patterned to form a trench (or second opening) in a position above the first conductive layer. The trench and the first opening together form an opening of the dual damascene structure. Finally, a second conductive material is deposited into the opening and the trench to form conductive lines and the dual damascene structures.

    Abstract: A dual damascene process for producing interconnects. The dual damascene process includes forming an etching stop layer over a substrate having a conductive layer therein, and forming an inter-layer dielectric layer over the etching stop layer. A mask layer is formed over the dielectric layer. The mask layer and the inter-layer dielectric layer are patterned to form an opening that expose a portion of the etching stop layer. The opening is formed above the conductive layer. Photoresist material is deposited over the mask layer and into the opening. The photoresist layer and the mask layer are patterned, and the photoresist material inside the opening is turned into a photoresist plug at the same time. A top layer of the photoresist plug is removed. Using the patterned photoresist layer and the mask layer as a mask, an anisotropic etching step is carried out to form a plurality of trenches inside the inter-layer dielectric layer. These trenches overlap with the opening. Metal is finally deposited into the opening and the trenches to complete the dual damascene process.
