Copper gettering at half the projected ion range induced by low-energy channeling He implantation into silicon
Fichtner, Paulo Fernando Papaleo; Behar, Moni; Kaschny, Jorge Ricardo de Araujo; Peeva, Anita; Koegler, Reinhard; Skorupa, Wolfgang (2000) [Artículo de periódico]He1 ions were implanted at 40 keV into Si <100> channel direction at room temperature (RT) and at 350 °C. The Si samples were subsequently doped with Cu in order to study the gettering of Cu atoms at the defective layer. ... -
Cu gettering in ion implanted and annealed silicon in regions before and beyond the mean projected ion range
Kögler, R.; Peeva, Anita; Lebedev, Andrei; Posselt, Matthias; Skorupa, Wolfgang; Özelt, G.; Hutter, Herbert; Behar, Moni (2003) [Artículo de periódico]The strong gettering of Cu atoms in single-crystal Si implanted with 3.5 MeV P+ ions is studied after thermal treatment and Cu contamination. Cu decorates the remaining implantation damage. Three separate Cu gettering ... -
Gettering of copper in silicon at half of the projected ion range induced by helium implantation
Peeva, Anita; Fichtner, Paulo Fernando Papaleo; Silva, Douglas Langie da; Behar, Moni; Koegler, Reinhard; Skorupa, Wolfgang (2002) [Artículo de periódico]Secondary ion mass spectroscopy, transmission electron microscopy, Rutherford backscattering /channeling spectrometry, and elastic recoil detection analysis measurements were used to determine the Cu gettering behavior ...
