Abstract

The boron uphill diffusion phenomenon, observed during the low-temperature annealing of ultrashallow junctions was discussed. The effect was found to be enhanced by preamorphization. An increase in the depth of the preamorphized layer was found to increase the transient enhanced diffusion in the tail and reduce the uphill diffusion in the high concentration portion.
