  • This paper discusses alloying effects on absorption and desorption kinetics of deuterium for Zr-Al alloys, studied with mass analyzed thermal desorption spectroscopy using a conventional high vacuum system. It is found that the absorption rate of deuterium was proportional to the 1/2 power of deuterium gas pressure. On the other hand, the desorption process obeyed the second order kinetics with respect to the amount of absorbed deuterium. The temperature dependence of the rate constants revealed that the activation energies for both the absorption and desorption processes were lowered by the increase in the Al content in the alloys. Through potentialmore » diagrams for the absorption and desorption of deuterium, it was also found that the heat of deuterium (hydrogen) solution decreased with increasing Al composition. In addition, the x-ray diffraction spectroscopy showed the formation of a Zr{sub 4}Al{sub 3} phase in the Zr{sub 3}Al{sub 2} sample owing to repeated absorption and desorption cycles. The results suggest that the electronic factors, for example, work function, electron density, d-band character and so on, play an important role for the alloying effects rather than crystallographic structures.« less
  • The gettering of some common impurities such as Fe, Cu, Al and Na in silicon wafers from low energy and high dose hydrogen ion implantation was studied. It is found that PIII is an effective and economic technique to integrate the gettering and doping processes and a very clean layer in the silicon wafers could be formed. Because hydrogen ions dominate in the hydride dopant plasma and H2 is usually used in PIII doping experiments as a dilution gas, low energy and high dose H-implantation introduces more effective gettering of the common impurities in Si. To optimize the implantation andmore » annealing conditions for the most effective gettering, suitable processing conditions were determined after investigating the influence on the gettering effect of changing implantation energy, dose, annealing temperature and annealing time, respectively.« less
  • Gettering means the removal of metallic impurities from the device-active area of the wafer by transport to a predesigned region-called gettering layer (GL). We introduce an interface at z = d{sub GL}, at which the effect of the gettering mechanism on the metal impurity distribution in the wafer is quantified, e.g. by specifying currents or by interfacial reactions of metal impurities, self interstitials etc. between GL and wafer. In response metal impurities will diffuse out of the wafer into the gettering layer. Following such a concept, in general three species of the metal impurity (M) are involved in gettering: M{submore » p} {l_arrow} M{sub i} {l_arrow} M{sub GL}. M{sub p} denotes immobile species in the wafer, which are precipitated into suicides or segregated at extended defects or whose diffusivity is too small to contribute noticeably to transport during the gettering procedure - like many substitutional metal species.« less
  • Research was carried out to find how the susceptibility of carbon-1/2 molybdenum steels to high-temperature hydrogen attack was affected by impurities contained in them and by stresses applied to them. As a result, it was learned that hydrogen attack was accelerated by the presence of nickel aluminium, phosphorus, and tin, and that intergranular cracking was promoted by stresses occurring in high-temperature hydrogen atmospheres.
  • Manganese was found to contribute to corrosion in Na/sub 2/SO/sub 4/--V/sub 2/O/sub 5/ melts and did not inhibit corrosion by forming higher melting compounds. Manganese also interfered with the corrosion inhibiting effects of magnesium and silicon. Calcium inhibited Na/sub 2/SO/sub 4/--V/sub 2/O/sub 5/ corrosion and the calcium--aluminium--silicon combination had good sodium tolerance. Calcium systems formed tenacious slags that detract from their corrosion inhibiting effectiveness. Measurements on the rare earth oxide mixtures, on zirconium, and on cerium did not indicate any corrosion inhibiting properties for these systems. (MCG)
