    摘要: The present invention provides a process of manufacturing a semiconductor device 200 while reducing silicon loss. In one aspect, the process includes removing a photoresist layer 270 from a semiconductor substrate 235 adjacent a gate 240 and cleaning the semiconductor substrate with a wet clean solution. The removing step includes subjecting the photoresist layer 270 to a plasma ash. The plasma ash removes at least a portion of a crust 275 formed on the photoresist layer 270 but leaves a substantial portion of the photoresist layer 270. The photoresist layer 270 is subjected to a wet etch subsequent to the plasma ash that removes a substantial portion of the photoresist layer 270.

    摘要: An integrated circuit and method of fabricating the same utilizing embedded silicon-germanium (SiGe) source/drain regions, and in which the proximity effect of nearby shallow trench isolation structures is reduced. Embedded SiGe source/drain structures are formed by selective epitaxy into recesses etched into the semiconductor surface, on either side of each gate electrode. The SiGe structures overfill the recesses by at least about 30% of the depth of the recesses, as measured from the interface between the channel region and the overlying gate dielectric at the edge of the gate electrode. This overfill has been observed to reduce proximity effects of nearby shallow trench isolation structures on nearby transistors. Additional reduction in the proximity effect can be obtained by ensuring sufficient spacing between the edge of the gate electrode and a parallel edge of the nearest shallow trench isolation structure.
