PHOTOSENSITIVE CERAMIC COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive ceramic composition capable giving a photo-cured sheet having an appropriate elastic modulus because it is necessary to ensure proper conditions after via hole formation in working of a subsequent step as well as to form high definition via holes having a high aspect ratio by photolithography so as to obtain satisfactory characteristics in a high-fre quency region. SOLUTION: The photosensitive ceramic composition comprises inorganic powders and photosensitive organic components essentially including a urethane compound containing an ethylenically unsaturated group and has 0.4-5 N/mm<2> tensile strength.
