ABSTRACTSingle crystalline YSZ and Y2O3 thin films are grown on Si(100) by e-beam evaporation. The amorphous S1O2 surface layer is removed in-situ by initially growing at low oxygen partial pressures in the case of YSZ or by first evaporating metallic Y for the growth of Y2O3. Epitaxy occurs by a solid state reaction after the SiO2 has been reduced by metallic Zr or Y. For Si/YSZ/Y2O3 the growth is cube on cube while in the case of Si/Y2O3/YSZ the oxide layers grow twinned in (110) orientation. XPS analysis and AES depth profiles reveal the reoxidation of the Si during further growth. Critical temperatures of 90 K and high current densities of 3.2×106 A/cm2 are measured on 150 nm thick YBCO films on SOS/YSZ/Y2O3 proving the excellent quality of the YBCO and the underlying buffer layers.

Interconnection technology is a key factor in the continual advancement of integrated systems. The rapid increase in device density and circuit complexity through scaling demands a similar increase in the interconnection density. Traditionally, this is achieved by reducing the metal pitch as well as gradually increasing the number of interconnection levels. As the width and spacing of interconnections are scaled down to submicron dimensions at the chip level and micron dimensions at the board level, signal delay, crosstalk, electromigration, and stress-induced migration become important concerns.Cu holds promise as an alternative metallization material to Al alloy due to its low resistivity and ability to reliably carry high-current densities. Cu has a bulk resistivity of 1.68 μΩ-cm, whereas Al has a bulk resistivity of 2.65 μΩ-cm. The only metal with a resistivity lower than Cu is Ag. Since Cu has a melting point and atomic weight both higher than Al, it is expected to have better resistance to electromigration, although properties such as grain structure and resistance to corrosion at high temperatures may also affect electromigration characteristics.

Thermal aging of Ni-12.8 at. % A1 and Ni-12.7 at. % Si produces spatially homogeneous dispersions of cuboidal γ'-Ni3Al or Ni3Si precipitate particles arrayed in the Ni solid solution. We have used 3.5-MeV 58Ni+ ion irradiation to examine the effect of irradiation during precipitation on precipitate morphology and distribution. The nearness of free surfaces produced unusual morphologies in foils thinned prior to irradiation. These thin-foil effects will be important during in-situ investigations of precipitation in the HVEM. The thin foil results can be interpreted in terms of observations from bulk irradiations which are described first.Figure 1a is a dark field image of the γ' precipitate 5000 Å beneath the surface(∿1200 Å short of peak damage) of the Ni-Al alloy irradiated in bulk form. The inhomogeneous spatial distribution of γ' results from the presence of voids and dislocation loops which can be seen in the bright field image of the same area, Fig. 1b.
