    摘要: A semiconductor device is fabricated with energy based process(es) that alter etch rates for dielectric layers within damascene processes. A first interconnect layer is formed over a semiconductor body. A first dielectric layer is formed over the first interconnect layer. An etch rate of the first dielectric layer is altered. A second dielectric layer is formed on the first dielectric layer. An etch rate of the second dielectric layer is then altered. A trench etch is performed to form a trench cavity within the second dielectric layer. A via etch is performed to form a via cavity within the first dielectric layer. The cavities are filled with conductive material and then planarized to remove excess fill material.

    摘要: The present invention facilitates semiconductor fabrication by providing methods of fabrication that selectively apply strain to multiple regions of a semiconductor device. A semiconductor device having one or more regions is provided (102). A strain inducing liner is formed over the semiconductor device (104). A selection mechanism, such as a layer of photoresist or UV reflective coating is applied to the semiconductor device to select a region (106). The selected region is treated with a stress altering treatment that alters a type and/or magnitude of stress produced by the selected region (108).
