A semiconductor device and a manufacturing method for the same are provided wherein the reliability of connections of fine metal wires connecting a second semiconductor chip to a wiring board can be improved in the case wherein the second semiconductor chip, which is located above the lower, first semiconductor chip, is significantly larger than the first semiconductor chip in a configuration wherein two semiconductor chips are stacked and mounted on a wiring board. In this semiconductor device the rear surface of the first semiconductor chip and the rear surface of the second semiconductor chip are adhered to each other by means of adhesive and the side of the adhesive is inclined from the edge portions of the first semiconductor chip toward the portions of the second semiconductor chip extending from the side of the first semiconductor chip. Therefore, it becomes possible to prevent the occurrence of microcracks in the second semiconductor chip and to prevent the occurrence of defective fine metal wire connections caused by the impact at the time of electrical connection of the second semiconductor chip to the wiring board.

摘要:
An exhaust pipe cooling system regulates the temperature of a exhaust system catalyzer on a small watercraft to ensure proper functioning and to inhibit overheating of the catalyzer. The cooling system supplies fresh water to a water jacket which surrounds the catalyzer in a manner independent of an engine cooling system. The cooling system also supplies fresh water to an upwardly oriented discharge nozzle. The upward water jet from the nozzle spays well above the surface of the body of water in which the watercraft is operated to provide a visible indicator of location of the small watercraft. A control valve regulate the flow rate of water through the cooling system to adjust the temperature of the catalyzer to fall within a desired range of operating temperatures. Under normal conditions, at least a majority of the water flows through the discharge nozzle; however, if the temperature of the catalyzer rises to an undesirably level, the control valve routes at least an increased portion of the water to the water jacket surrounding the catalyzer.
