摘要： A method for fabricating a semiconductor device to lower source/drain sheet resistance is provided. A dielectric layer with a plurality of contact windows is formed on a semiconductor device. Next, selective epitaxial growth (SEG) is implemented, and then a metal layer is sputtered. After that, a silicide is formed by heat treatment. In another embodiment, selective epitaxial growth is implemented first, and then a dielectric layer with a plurality of contact windows is formed. Then, a metal layer is sputtered, and a silicide is then formed by heat treatment. Since the silicide is formed by way of SEG, the silicon substrate will not be consumed during the process of forming the silicide, and the depth of the junction region is maintained, and the source/drain sheet resistance is lowered.

摘要： A method for forming interconnection plugs comprising the steps of providing a substrate having a dielectric layer formed thereon, wherein an opening exposing a pad area for connection with other structures is also formed in the dielectric layer. Next, a glue layer is formed over the pad area and the dielectric sidewalls of the opening. Subsequently, plug material is deposited into the opening forming a plug layer. This is followed by etching back the plug layer to return the plug material inside the opening to a level below the height of the dielectric layer. Then, a selective etching method having a high selectivity ratio between the dielectric layer and the plug layer is used to etch the dielectric layer. Finally, the dielectric layer and the plug layer are etched to almost the same level of height. The characteristic of this invention is the utilization of the higher etching r!ate of dielectric material with respect to the plug material so that the dielectric layer is etched back to the same level of height as the plug layer. Hence, the formation of recesses on the plug surface and the surface of subsequently deposited metallic layer is avoided.
