Atomistic simulations of extrinsic defects evolution and transient enhanced diffusion in silicon

摘要

We present a "unified" model for the simulation of boron transient enhanced diffusion in both crystalline and preamorphised structures. The model describes the thermal evolution of a supersaturation of Si interstitial atoms in dynamical equilibrium with all types of extrinsic defects. We show some successful applications of our model to a variety of experimental conditions and give an example of its predictive capabilities at ultra low implantion energies.
