Web摘要： An analysis of the conditions for obtaining oxidation‐enhanced or retarded dopant diffusions (OED or ORD), in accordance with the stacking fault growth/shrinkage phenomena, is carried out for the oxidation of Si by assuming that vacancy and Si self‐interstitials coexist at high temperatures and that during oxidation a local equilibrium … WebAn atmospheric pressure oxidation cycle representative of bipolar, metal-oxide-silicon (MOS) and CMOS technologies is included. This Practice reveals strain fields arising from the presence of precipitates, oxidation induced stacking faults, and shallow etch pits.
WebAbstract. Oxidation induced stacking faults have been observed to function as dislocation generating sources in silicon single crystals when the crystals are annealed at high temperatures. The presence of diffused boron in the silicon results in a large increase in the size of the dislocation colonies generated from the faults. WebDec 14, 2015 · In general, when the Si emission into the substrate due to oxidation is enhanced and the Si interstitials are accumulated near the oxidizing interface, an extrinsic stacking fault, termed oxidation-induced stacking fault (OSF), is formed, 24 24. S. T. Dunham and J. D. Plummer, J. Appl. Phys. 59, 2551 (1986).
