Abstract:
Raman and spreading resistance profiling have been used to analyze defects in germanium caused by hydrogen and helium
implants, of typical fluences used in layer transfer applications. Beveling has been used to facilitate probing beyond the laser
penetration depth. Results of Raman mapping along the projection area reveal that after post-implant annealing at 400?C, some
crystal damage remains, while at 600?C, the crystal damage has been repaired. Helium implants create acceptor states beyond the
projected range, and for both hydrogen and helium, 1 1016 acceptors/cm2 remain after 600?C. These are thought to be vacancyrelated
point defect clusters.
