    Notes:
    By employing stress compensation technology in conjunction with an ultrahigh vacuum ion implanter, we have obtained two orders of magnitude smaller reverse-bias current levels in n+p junctions annealed at 550 °C as compared to the previous data. When samples are made with an optimum stress compensation condition, the magnitude of reverse-bias currents in n+p junctions as well as the carrier deactivation during post-implantation anneal becomes smallest. In order to further reduce the reverse-bias current level, it is shown that the elimination of contamination involvement during the implantation process is most essential.

    Notes:
    Reduction in the reverse-bias current in low-temperature-annealed silicon pn junctions has been studied. It has been shown that the transition region existing underneath the ion-implantation-generated amorphous layer and the contamination incorporated into this region play a decisive role in determining the reverse current level. In order to minimize the contamination involvement into the transition region, ultraclean ion-implantation technology has been developed. Ion implantation was carried out under a UHV (5×10−10 Torr) condition in order to minimize the recoil implantation of adsorbed contamination at the surface. The contamination due to the high-energy ion-beam sputtering of component parts in the ion implanter has also been suppressed. As a result, a low reverse-bias current level of about 1.2×10−7 A/cm2 has been obtained for arsenic-implanted n+p junctions annealed at 550 °C, which is more than two orders of magnitude smaller than that previously reported. The stress compensation technology employing combined implantation of phosphorus and arsenic has also been shown to be very effective in reducing the lattice strain and in suppressing the damage generation.

    Notes:
    Lipopolysaccharides (LPSs) were isolated from Actinobacillus actinomycetemcomitans strains ATCC 29523 (serotype a), Y4 (b), and NCTC 9710 (c) by the hot phenol-water procedure. Y4 lipid A was obtained by the hydrolysis of Y4 LPS in 1 % acetic acid. All the LPS preparations and Y4 lipid A were mitogenic for C3H/HeN mouse spleen cells, but not for C3H/HeJ mouse spleen cells. Immuno-globulin preparations partially purified by ammonium sulfate precipitation at 33% saturation from rabbit antisera against Y4 whole cells inhibited the mitogenic response of C3H/HeN mouse spleen cells to LPSs from all the strains of A. actinomycetemcomitans and Y4 lipid A. Anti-Y4 LPS immunoglobulin preparation inhibited the mitogenic acuvity of Y4 LPS and Y4 lipid A. Furthermore, anti-Y4 whole cell Fab fragments inhibited the mitogenic activity of both Y4 LPS and Y4 lipid A. These results suggest that antibodies against A. actinomycetemcomitans LPS may modify immune responses of lymphocytes to this organism at periodontal sites.
