摘要： A multilayer thin film of the invention has an oxide thin film formed on a semiconductor single crystal substrate, and the oxide thin film includes at least one epitaxial thin film composed mainly of zirconium oxide or zirconium oxide stabilized with a rare earth metal element (inclusive of scandium and yttrium). Included is an oriented thin film formed on the oxide thin film from a dielectric material of perovskite or tungsten bronze type with its c-plane unidirectionally oriented parallel to the substrate surface. Consequently, there are provided a perovskite oxide thin film of (001) orientation, a substrate for an electronic device comprising the thin film, and a method for preparing the thin film.

摘要： A multilayer circuit board comprises core layers 101 and 102 made of a core material impregnated with resin, resin layers 111 and 112 interposed between the core layers 101 and 102, a wiring pattern 140 embedded in the resin layers 111 and 112. The core layers 101 and 102 have a thickness of 100 μm or smaller, whereby the entire board can significantly be thinned. Furthermore, the less strong resin layers 111 and 112 are interposed between the hard core layers 101 and 102, whereby the entire board has increased strength.
