摘要： A semiconductor chip 1 is provided with a first electrode 2 formed at a first corner of a crystal substrate 1a generally quadrangular as viewed in plan, and with a second electrode 3 formed to extend along two sides of the crystal substrate 1a, these sides including between them a second corner located diagonally away from the first corner. The first electrode 2 and the second electrode 3 are connected to a first lead 15 and second leads 16a, 16b formed on the circuit substrate 10 via solder paste 20. The narrow first lead 15 extends transversely to a side of the crystal substrate 1a, and the second leads 16a, 16b extends in the opposite direction to that of the first lead 15. The first lead 15 and the second lead 16b are offset from each other by an appropriate distance. With such arrangements, the surface tension of melted solder prevents the semiconductor chip 1 from being fixed to the circuit substrate 10 with a slanting posture.

摘要： A semiconductor light-emitting device has a semiconductor light-emitting element 3 mounted on an electrode 2 formed on a surface of an insulating substrate 1, and has a reflective case 5 provided on the insulating substrate 1 so as to reflect the light from the light-emitting element 3, with the space inside the reflective case 5 sealed with a translucent resin 6. The reflective case 5 has a grained portion 51 formed over at least part of the surface thereof over which it makes contact with the translucent resin 6. This effectively prevents the translucent resin from coming off the reflective case. To enable the semiconductor light-emitting device to emit light with more even intensity in all directions, the grained portion is formed, preferably, at least in the portions of the reflective case 5 that face the side surfaces of the semiconductor light-emitting element.
