Rapid thermal annealing of high concentration, arsenic implanted silicon single crystals

Rapid thermal annealing of arsenic implanted 〈100〉 silicon single crystals has been studied by Rutherford backscattering/channeling spectrometry, and Hall effect/resistivity measurements, combined with layer removal. Redistribution of the implanted arsenic was followed as a function of anneal time (6–60 s including temperature rise time) and implanted peak concentration (3–10×1020 cm−3) at temperatures of 1050 and 1090 °C. The maximum …
