Abstract :
The authors demonstrated that the combination of VPD and LA enables the fabrication of high quality, defect-free USJs with abrupt dopant profile. The results for PMOS with B-VPD are very promising for the 32 nm and the 22 nm technology nodes. In the case of NMOS, As-VPD and LA enable the fabrication of an USJ but the electrical deactivation of a large part of the in-diffused dopants is responsible for the high sheet resistance values.
