    Notes: The crystallographic texture of electroplated Cu in damascene trenches has been examined by x-ray diffraction pole figure analysis. The influence of two post-plating treatments on the resulting orientation of (111) planes of the Cu inside the trenches are compared. When the as-deposited small-grained Cu is allowed to recrystallize at room temperature before chemical mechanical polishing of the overlying Cu, we observe only a (111) fiber texture of the Cu inside the trenches. In contrast, when the overlying material is polished away before recrystallization of the small-grained Cu, pole figures show evidence of sidewall texture of the (111) planes in addition to the (111) fiber texture in the as-deposited as well as the annealed state. The presence or absence of a sidewall texture component in the pole figures offers insight into the evolution of the microstructure of damascene Cu. © 1999 American Institute of Physics.

    Notes: Die Kompression des Rückenmarkes oder der Cauda equina ist eine gefürchtete Komplikation bei Krebspatienten. Sie läßt sich autoptisch bei etwa 5% aller Tumorpatienten nachweisen und ist aufgrund ihrer klinischen Problematik wie Parese der unteren Extremitäten oder Verlust der Blasen- und Mastdarmkontrolle ein akut zu behandelnder onkologischer Notfall.

    Notes: Abstract Antiferromagnetic resonance (AFMR) measurements on a well characterized single crystal sample of MnF2 have been performed using various kinds of millimeter and submillimeter sources up to 570 GHz and a superconducting magnet up to 20 T. All the AFMR modes predicted from the theory have been observed. We report a complete frequency-field chart for these AFMR modes.

    Notes: Abstract. nitrides by laser-induced molecular beam epitaxy (LIMBE). The requirements for the formation of high-quality, monocrystalline layers are much stronger than those for polycrystalline films. We have modified and improved the conventional pulsed laser deposition. In our process, we use metallic targets in a nitrogen environment instead of ceramic or pressed powder nitrides and we employ picosecond laser pulses with high energy (〉1 mJ) and high repetition rate (2 kHz). We have grown GaN, AlN, InN, InGaN and Mg-doped GaN on sapphire (0001).

    Notes: Abstract Residual gas analysis (RGA) and optical emission spectroscopy have been evaluated as potential in situ techniques for the detection of plasma-induced polymer surface etching. The detection is based on the measurement of CO and CO2 species formed in the gas phase following oxidation of the etching fragments released from the polymer surface. Experiments were performed on poly(ethylene terephthalate) and UV-cured acrylic (tripropylene glycol diacrylate) films exposed to O2 RF (13.56 MHz) plasmas. A linear correlation is obtained between the formation of CO and the polymer etching rate over the entire experimental range, but discrepancies appear for the formation of CO2 at high treatment powers (etching rate 〉 1.0 μg/min.cm2). This behavior is attributed to a deficit of oxidizing agents relative to the generation of etching fragments. The results suggest that both RGA and optical emission spectroscopy can be used to monitor in situ and in real-time the etching of polymer surfaces during plasma treatment.
