ABSTRACTTitanium and many of its alloys show very poor wear resistance considering their hardness. This together with high thermodynamic driving forces to form very hard compounds between titanium and nitrogen or carbon made titanium based alloys obvious candidates for ion implantation. In this paper the effects of similar implanted concentration profiles of nitrogen and carbon in two titanium alloys are compared. The wear behavior of pin on disk wear tests are reported along with the ultramicrohardness of the four samples.

As an alternative to the use of cross-sectioned specimens, a method which uses backthinned specimens has been developed for the measurement of concentration profiles in ion-implanted materials. The technique is less direct but avoids the sometimes insurmountable problems associated with the preparation of suitable cross-sectioned specimens and is more applicable to low-energy implants where the penetration depth is small. A series of x-ray spectra is measured in a wedge-shaped, backthinned foil.

ABSTRACTRapid thermal annealing (4−7s) of 28Si and 9Be implants in VPE-grown In0.53Ga0.47As has produced n- and p-type active layers with controlled doping levels between 1017 and 3×1018 cm−3. The multiple-implant schedules were based on Rp and ΔR data derived from SIMS measurements on single-energy implants. The activated n- and p-type layers have a good surface morphology and 300 K mobilities of 3000–7000 and 100–200 cm2 /V−s, respectively. Data on implant schedules, electrical characteristics, carrier concentration profiles, and Rp /ΔRp information are presented.

ABSTRACTGood quality p+/n and n+/p shallow junctions (< 0.15 um) with reverse current density of few nA/cm2 and low contact resistivity (∼ 5×10–7 Ω cm2) have been fabricated by using Mo suicide and Rapid Thermal Annealing (RTA). The processes of implantation through Mo films and into MoSi2 layers have been comparatively analysed on the basis of SIMS and carrier concentration profiles, TEM observations and DLTS measurements. In the case of n+/p diodes fabricated by ITM technology slightly worse leakage currents have been observed, in spite of the better planarity of the silicide-silicon interface exhibited by these structures.
