    Notes: Abstract. The solution deposition of YBa2Cu3O7-δ (Y123) high temperature superconducting thin films was studied. The films were prepared from a polymer-containing precursor onto SrTiO3 (001) and LaAlO3 (001) substrates and mineralized at high temperatures. The process depended on details of the film preparation in a delicate fashion, resulting either in superconducting or non-superconducting thin films. To elucidate this difference in conductivity, scanning electron microscopy and several X-ray diffraction techniques were used to characterize the resulting Y123 layers. Both the morphology of the film and the percentage of non-superconducting minority components are likely to be the origin of the difference in the conductance behavior at low temperatures.

    Description / Table of Contents: XPS investigations and determination of the electron beam sensitivity revealed a crosslinking mechanism via halogen elimination. The crosslinking effect is higher with an admixture of bisazide. The halogen elimination induced by irradiation of the 4-halogenphenol novolac resists increases in the order fluorine, chlorine, bromine, iodine.
    Notes: XPS-Untersuchungen und die Bestimmung der Elektronenstrahlempfindlichkeit an Halogenphenolnovolak-Resistschichten ergaben, daß ein Vernetzungsmechanismus über Halogeneliminierung abläuft. Durch Bisazidzusatz wird der Vernetzungseffekt erhöht. Die strahlenchemisch induzierte Halogeneliminierung der untersuchten 4-Halogenphenolnovolake steigt in der Reihenfolge Fluor-Chlor-Brom-Iod.
