摘要： A gate insulating film (13) and a gate electrode (14) of non-single crystalline silicon for forming an nMOS transistor are provided on a silicon substrate (10). Using the gate electrode (14) as a mask, n-type dopants having a relatively large mass number (70 or more) such as As ions or Sb ions are implanted, to form a source/drain region of the nMOS transistor, whereby the gate electrode (14) is amorphized. Subsequently, a silicon oxide film (40) is provided to cover the gate electrode (14), at a temperature which is less than the one at which recrystallization of the gate electrode (14) occurs. Thereafter, thermal processing is performed at a temperature of about 1000° C., whereby high compressive residual stress is exerted on the gate electrode (14), and high tensile stress is applied to a channel region under the gate electrode (14). As a result, carrier mobility of the nMOS transistor is enhanced.

摘要： A method of manufacturing a semiconductor device is provided which can suppress leakage current increases by making into silicide. Impurity that suppresses silicide formation reaction (suppression impurity), such as germanium, is introduced into source/drain regions (16, 36) from their upper surfaces. In the source/drain regions (16, 36), a region shallower than a region where the suppression impurity is distributed (50) is made into silicide, so that a silicide film (51) is formed in the source/drain regions (16, 36). Thus, by making the region shallower than the region (50) into silicide, it is possible to suppress that silicide formation reaction extends to the underside of the region to be made into silicide. This enables to reduce the junction leakage between the source/drain regions (16, 36) and a well region.
