Electronic device and method of fabricating the same

Publication number: 20050194626

Abstract: The electronic device includes a substrate, a lower conductive film provided on the substrate, a functional film provided on the lower conductive film, and a crystallinity barrier film provided between the lower conductive film and the functional film. The present invention prevents the crystallinity of the functional film being affected by the crystallinity or the material selection of the lower conductive film, so it becomes possible to use a low-cost metal such as aluminum (Al) for the lower conductive film, and to use a low-cost method for forming the film, thereby making it possible to improve the crystallinity of the functional film without using a costly film-formation method such as epitaxial growth. For the crystallinity barrier film, there can be used a material having an amorphous structure.

Process for preparation of 2-aminotetralin derivatives and intermediates thereof

Publication number: 20050153408

Abstract: The present invention is to efficiently and simply prepare an optically active 7-substituted-2-aminotetralin with industrial advantage. In the process, a 7-substituted-2-tetralone or its bisulfite adduct is reduced with a microorganism to an optically active 7-substituted-2-tetralol. Then, a sulfonyl group is introduced to the hydroxy group to form an optically active 7-substituted-2-sulfonyloxytetralin. Then, with inversion of the configuration, a nitrogen substituent is introduced using a nitrogen nucleophile to form an optically active 2,7-substituted tetralin. Furthermore, if necessary, the nitrogen substituent is converted into a non-substituted amino group. Thus, an optically active 7-substituted-2-aminotetralin or its salt is prepared.

Gas refining system

Patent number: 6896858

Abstract: A gas refining method for adsorbing a reducing gas obtained by pressure gasification of coal or oil comprises introducing a reducing gas stream into an adsorbing and removing zone where it contacts an adsorbent. Sulfur-containing compounds are adsorbed onto the adsorbent and a first oxygen-containing gas stream is introduced into the adsorbing and removing zone in order to form a regeneration gas containing sulfur dioxide. The regeneration gas is contacted with a second oxygen-containing stream and a calcium-containing liquid slurry to effect absorption of sulfur dioxide by the slurry and precipitation of a gypsum compound. The temperature of the slurry is varied to cause selective precipitation of 60 -gypsum hemihydrate or gypsum dihydrate.

Film bulk acoustic wave resonator wafer and method of fabricating a film bulk acoustic wave resonator

Publication number: 20050104689

Abstract: A film bulk acoustic wave resonator wafer of the present invention prevents electric discharge from occurring in the process of fabricating a film bulk acoustic wave resonator, thereby enhancing product reliability and yield. The film bulk acoustic wave resonator wafer of the present invention comprises a substrate, a lower electrode and an upper electrode provided on the substrate and a piezoelectric film provided between the lower electrode and upper electrode. The lower electrode and upper electrode are shorted through a window provided in the piezoelectric film. Since the lower electrode and upper electrode are therefore kept at the same potential, no electric discharge passing through the piezoelectric film occurs even during the formation of a protective film covering the upper electrode, dicing of the substrate and other processes in which discharge has heretofore been likely to occur.
