H. Erramli et al., STUDY OF THE OXYGEN BEHAVIOR IN THERMALLY TREATED CZOCHRALSKI SILICONBY COMBINING CPAA WITH ION CHANNELING, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 117(3), 1996, pp. 283-288
Non-doped Czochralski grown silicon substrates for microelectronic dev
ices contain relatively high oxygen concentrations (5 X 10(17)-10(18)
atoms/cm(3)). Reduction of the oxygen content near the crystal surface
is obtained by internal gettering treatments. Ion channeling and char
ged particle activation analysis (CPAA) were combined to determine the
concentration and position of oxygen atoms in the silicon lattice. Th
e influence of the internal gettering treatment parameters on concentr
ation and position of oxygen atoms in the silicon lattice has been inv
estigated. The O-16(He-3,p)F-18 nuclear reaction was used and the F yi
eld was measured by direct gamma-ray spectrometry.
