    Abstract: The present invention relates to a semiconductor device comprising at least one n-channel field effect transistor (n-FET). Specifically, the n-FET comprises first and second patterned stressor layers that both contain a carbon-substituted and tensilely stressed single crystal semiconductor. The first patterned stressor layer has a first carbon concentration and is located in source and drain (S/D) extension regions of the n-FET at a first depth. The second patterned stressor layer has a second, higher carbon concentration and is located in S/D regions of the n-FET at a second, deeper depth. Such an n-FET with the first and second patterned stressor layers of different carbon concentration and different depths provide improved stress profile for enhancing electron mobility in the channel region of the n-FET.

    Abstract: Expitaxial substitutional solid solutions of silicon carbon (101 ) can be obtained by an ultra-fast anneal of an amorphous carbon-containing silicon material. The anneal is performed at a temperature above the recrystallization point, but below the melting point of the material and preferably lasts for less than 100 milliseconds in this temperature regime. The anneal is preferably a flash anneal or laser anneal. This approach is able to produce epitaxial silicon and carbon-containing materials (101 ) with a substantial portion of the carbon atoms at substitutional lattice positions. The approach is especially useful in CMOS processes and other electronic device manufacture where the presence of epitaxial Si1-yCy, y

Such an n-FET with the first and second patterned stressor layers of different carbon concentration and different depths provide improved stress profile for enhancing electron mobility in the channel region of the n-FET.
