Abstract
Arsenic, antimony, and bismuth have been diffused into (111) silicon from doped expitaxially deposited source layers in a flowing hydrogen atmosphere. Under intrinsic conditions, the dopant profiles show excellent Fickian behavior. The diffusion coefficients, obtained as a function of temperature, can be described by the following equations: /sec; /sec; and /sec. These data, together with those of phosphorus reported earlier, are shown to be consistent with a point-defect mechanism that involves a closely coupled vacancy-impurity ensemble.
