The polyatomic cluster, decaborane (B10H14), was used to form very shallow p+ junctions. During annealing at 900C, the diffusion of 3keV B atoms was strongly suppressed as compared with that of 10keV-implanted B. The different annealing behaviors were attributed to the differing defect distributions which were produced by 10 and 3keV implantation.
