Websuch as silicon. The diffusion of mainly in-terstitially dissolved foreign atoms (A i), like hydrogen or the 3d transition elements in silicon, proceeds via interstitial lattice sites. No intrinsic point defects are involved in this direct interstitial mechanism. Direct diffusion of atoms on substitu-tional sites (A s) can occur by means of a WebThe reactions among self-interstitials (Sii), vacancies (V), impurities (C, 0), and dopants (B, P) in Si produce undesirable defects which affect device operation and control transport processes such as dopant diffusion. Electron beam irradiation has been used to generate Sii and V to initiate the defect reactions.
