Title: Structure and method for mounting semiconductor devices

Abstract: A structure and method of mounting semiconductor devices which can cope with miniaturization and high-speed transmission by embedding a semiconductor device within a wiring layer or transmission path formed between opposite sides of a substrate even when a plurality of semiconductor devices are mounted on the substrate. A semiconductor device is interposed between wiring layers or transmission paths formed on opposite sides of a substrate, thereby shortening the distance between the wiring layers and rendering a structural body compact oerall. As a result of shortening of the distance between the wiring layers, the electrical resistance value of the structural body can also be diminished. Consequently, the electrical characteristic of the mount structural body can be improved, and high-speed transmission becomes feasible. Alternatively, a semiconductor device is cylindrically formed so as to enclose a conductive wire, thereby realizing a high electrical characteristic. External terminals can be led from the entire side surface of the cylindrical structural body, thereby increasing the number of external terminals per unit mount area and rendering the structural body compact.
