A method and a structure is provided for mounting a semiconductor device by the bump technique using compound metallic ultra-fine particles each comprising a core portion consisting substantially of a metallic component, and a coating layer chemically bound to the core portion and comprising an organic substance. The method and the structure are characterized by using one of, or a combination of, the following two bump technologies: 1) Forming under bump metals from the compound metallic ultra-fine particles, and forming ordinary solder balls on the under bump metals. 2) Using paste balls comprising the compound metallic ultra-fine particles, instead of ordinary solder balls. <IMAGE> <IMAGE> |
