    摘要： Provided is a method of manufacturing a semiconductor device, which is adapted to prevent the deposition of a material on a laser light emitting edge, thereby enabling an improvement in longevity characteristics of a laser. A base having a laser chip mounted thereon is irradiated with an energy beam having a shorter wavelength than an oscillation wavelength of the laser chip. Photolysis and oxidation caused by the energy beam cause the removal of an adherent from the overall base or the deterioration thereof, and incidentally, the adherent is derived from an adhesive sheet used to attach the laser chip to the base, or the like. Preferably, laser light or ultraviolet light, for example, is used as the energy beam. Alternatively, the base having the laser chip mounted thereon may be irradiated with plasma so as to remove the adherent utilizing an ion cleaning effect of the plasma. After irradiation, a top is mounted to the base so as to shut off the laser chip from the outside.

    摘要： A semiconductor device such as a light emitting semiconductor device comprising a mask layer having opening areas and a selective growing layer comprising a semiconductor grown selectively by way of the mask layer, with each of the mask layer and the selective growing layer being disposed by two or more layers alternately. The semiconductor device is manufactured by a step of laminating on a substrate a mask layer having opening areas and a selective growing layer comprising a semiconductor grown selectively way of a mask layer, each by two or more layers alternately and a subsequent step of laminating semiconductor layers thereon. Threading dislocations in the underlying layer are interrupted by the first mask layer and the second mask layer and do not propagate to the semiconductor layer. The density of the threading dislocations is lowered over the entire surface and the layer thickness can be reduced.
