Dj. Bennett et Te. Price, TRANSIENT ENHANCED DIFFUSION DURING POSTIMPLANT ANNEALING OF SILICON, Semiconductor science and technology, 9(8), 1994, pp. 1535-1542
A method for calculating diffusion enhancement due to dopant-defect pa
iring in ion-implanted silicon is described. The number of dopant-defe
ct pairs is calculated from a general defect clustering model. The ass
umption that a net dopant flux arises from dopant-defect pair gradient
s leads to the calculation of an initial enhanced diffusion coefficien
t. This diffusion enhancement is shown to be consistent with measured
transient diffusion.
