A quantitative.study about the.the.mal.activation of the.mal.donors (TD) in high re.istivity magne.ic czochral.ki (Mcz) sil.con was carrie. out. The.samp.e. are.p./p.n+ diode. (active.are. 0.25 cm(2), thickne.s 300 mu m) made.of Mcz p.typ. Si wafe.s with the.re.istivity of about 2 k Ome.a-cm. The.conce.tration of inte.stitial.oxyge. (O-i) in this mate.ial.was me.sure. by the.Fourie. transformation infrare. (FTIR) sp.ctroscop. me.hod and it is 4.9 x 10(17) cm(-3). The.TD activation was p.rforme. through an isochronal.the.mal.tre.tme.t at 430 de.re.s c up.to a total.time.of 120 min. The.sp.ce.charge.de.sity afte. e.ch anne.l.ng ste.0}was e.tracte. from cap.citance.vol.age.(cV) me.sure.e.ts. The.TD ge.e.ation can be.util.ze. in p.oce.sing of sil.con de.e.tors (p.xe., strip.and drift de.e.tors) that are.use. e.g. in sp.ce.ap.l.cations, high-e.e.gy p.ysics e.p.rime.ts, and se.e.al.visual.imaging ap.l.cations. If the.starting mate.ial.is boron-dop.d p.typ. high-re.istivity cz-Si, the.TD ge.e.ation p.oce.s can be.util.ze. in orde. to p.oduce.p./n-/n+ de.e.tors. The.l.st the.mal.p.oce.s ste.0} i.e. the.sinte.ing of al.minum, is inte.tional.y carrie. out at the.te.p.rature.whe.e.TD's are.cre.te.. Due.to the.ge.e.ate. donors, the.p.typ. bul. wil. e.e.tual.y be.comp.nsate. to n-typ. bul..
