Notes:
We observe the anomalous diffusion of lightly implanted As into Si substrate during conventional furnace anneal in nitrogen ambient. The anomalous behavior shows two conspicuous features in the near-surface region and in the tail region. In the near-surface region reaching about 30–50 nm from the interface, a large number of As atoms moves toward the oxide/Si interface, and occasionally accumulates in a narrow region about 10–20 nm from the interface. Retarded diffusion is observed in the tail region. The diffusivity in the tail region increases with the increase of annealing time.
