Abstract
The likelihood of forming silicon germanium abnormal growths, which can be undesirably formed on the gate electrode of a strained-channel PMOS transistor at the same time that silicon germanium source and drain regions are formed, is substantially reduced by using protection materials that reduce the likelihood that the gate electrode is exposed during the formation of the silicon germanium source and drain regions.
