Abstract
Boron and phosphorus were implanted into (100) Ge with energies ranging from 20-320 keV and doses of 5×1013 to 5×1016 cm-2. The as-implanted and annealed dopant profiles were examined using secondary ion mass spectrometry (SIMS) and spreading resistance profiling (SRP). The first four moments were extracted from the as-implanted profile for modeling with Pearson distributions over the entire energy range. The samples were annealed at 400, 600, or 800°C in nitrogen ambient. The dopant activation and diffusion were also examined and it was found that p-type sheet resistances immediately after boron implantation as low as 18 ohms/sq could be obtained without subsequent annealing.
