    Description / Table of Contents: Corrosion-resistant, hermetic microelectronic packages for aerospace applicationsCorrosion-resistant, high reliable aerospace electronics need expensive ceramic substrates, noble metal conductors and very clean stainless steel or ceramic packages. The requirements, material technologies, problems and more economical packages are described.
    Notes: Zur Vermeidung von Korrosionsschäden an Sicherheitselektroniken der Luft- und Raumfahrt sowie der Wehrtechnik werden vorzugsweise Keramik-Substrate und Edelmetall-Leiter sowie völlig feuchte- und salzfreie, hermetisch verschlossene Metall oder Keramikgehäuse verwendet. Die Anforderungen, Materialien, Technologien und Probleme der hermetischen Mikroelektronik-Verpackung wird im folgenden Aufsatz näher beschrieben werden.

    Description / Table of Contents: Investigation of CuGaSe2 and CuGaTe2 under High PressureThe X-ray powder diffraction analysis at 300 K in dependence on the pressure gives a transition from the chalcopyrite-type to the NaCl structure for CuGaSe2 at 12.5 GPa and for CuGaTe2 at 8 GPa. The phase transition is associated with a discontinuity of the volume of 8.6 and 3.8%. These results were discussed in relation to other tetrahedrally coordinated compounds.
    Notes: Röntgenuntersuchungen bei 300 K in Abhängigkeit vom Druck ergaben, daß CuGaSe2 bei 12,5 GPa und CuGaTe2 bei 8 GPa von der Chalcopyrit-Struktur in die NaCl-Struktur übergehen. Dabei tritt ein Volumensprung von 8,6 bzw. 3,8% auf. Diese Ergebnisse werden im Zusammenhang mit Hochdruckuntersuchungen an anderen tetraedrisch koordinierten Verbindungen diskutiert.
