| 摘要 |
The present invention discloses a semiconductor source/drain contact structure, which comprises a substrate, a source/drain region disposed in the substrate, at least one non-silicided conductive layer including a barrier layer disposed over and in contact with the source/ drain region, and one or more contact hole filling metals disposed over and in contact with the at least one non-silicided conductive layer, wherein a first contact area between the at least one non-silicided conductive layer and the source/drain region is substantially larger than a second contact area between the one or more contact hole filling metals and the at least one non-silicided conductive layer.
