Abstract
The time evolution of B, As, and In doping profiles during and after solid phase epitaxial regrowth (SPER) was monitored for conditions applicable to sub-65 nm CMOS technologies. As and In segregate during SPER by a sweep of the regrowing interface. In the case of B, significant B diffusion in a-Si occurs during SPER, while afterwards B uphill diffusion dominates. With the aid of atomistic simulation we have identified a temperature dependent time to maximum uphill B diffusion.
