Inventor: LIOU JR-JIAN
IPC: H01L21/768
Filed: 2000-08-21
Granted: 2001-11-21
Abstract: A dual damascene process of low dielectric constant comprises the following steps. Provide a substrate, deposit a copper diffusion barrier layer on the substrate, and then deposit a first inter-metal dielectric layer on the diffusion barrier layer. Subsequently, cover the first inter-metal dielectric layer sequentially to form an etching stop layer, a second dielectric layer, and a hard mask layer. Then, a first photoresist layer is formed above the hard mask, followed by defining the first photoresist layer. Using the first photoresist layer as the mask and performing a dry etching process. Sequentially etch through the hard mask layer, the second dielectric layer, stop layer, and the first dielectric layer to form an interlayer hole, and then remove the first photoresist layer and the hard mask layer. Above the second dielectric layer and within interlayer hole, a conventional partial solidification or non-solidification spin-on glass is filled as the filler material. Subsequently, perform etch back for the filler material to expose the surfaces of the second inter-metal dielectric layer and the filler material, and deposit an anti-reflection layer thereon. Then, a second photoresist layer is formed above the anti-reflection layer, followed by defining the second photoresist layer. Using the second photoresist layer as the mask to perform a dry etch process, and use the etch stop layer as the etching end to remove partial portion of the surface exposed from the anti-reflection layer and form a groove. Subsequently, remove the second photoresist layer to form an opening of the damascene. Then, along the contour of the damascene opening, forms a barrier layer made of tantalum nitride in conformal fashion that extends to cover the surface of the inter-metal dielectric layer. Lastly, perform a process of manufacturing interconnects.
