| 摘要 |
The present invention allows the manufacturing of field effect transistors with reduced thermal budget. A first amorphized region and a second amorphized region are formed in a substrate adjacent to the gate electrode by implanting ions of a non-doping element, the presence of which does not significantly alter the conductive properties of the substrate. The formation of the amorphized regions may be performed before or after the formation of a source region, a drain region, an extended source region and an extended drain region. The substrate is annealed to achieve solid phase epitaxial regrowth of the amorphized regions and to activate dopants in the source region, the drain region, the extended source region and the extended drain region.
