Ba. Andreev et al., FORMATION OF NEW DONORS AS A RESULT OF HEAT-TREATMENT OF SILICON WITHDIFFERENT OXYGEN CONCENTRATIONS, Semiconductors, 27(4), 1993, pp. 315-323
The formation of ''new'' donors in silicon with different oxygen conce
ntrations at a temperature T=600-degrees-C has been analyzed. It was f
ound that the energy spectrum of new donors is a composite spectrum wh
ose components have been determined. A study of new donors revealed th
at the thermal stability of the ''classical'' double thermal donors fo
rmed at T=450-degrees-C is much higher than that assumed in the curren
t literature. The formation of new donors depended strongly on the int
ital oxygen concentration.
