A method and laser system effect rapid removal of material from a workpiece by applying heating energy in the form of a light beam to a target location on the workpiece to elevate its temperature while maintaining its dimensional stability. When the target portion of the workpiece is heated, a laser beam is directed for incidence on the heated target location. The laser beam preferably has a processing laser output that is appropriate to effect removal of the target material from the workpiece. The combined incidence of the processing laser output and the heating energy on the target location enables the processing laser output to remove a portion of the target material at a material removal rate that is higher than the material removal rate achievable when the target material is not heated.

A semiconductor light emitting device is formed by adhering a semiconductor layered portion having a light emitting layer forming portion to a conductive substrate via a metal layer. The metal layer has at least a first metal layer for ohmic contact with the semiconductor layered portion, a second metal layer made of Ag, and a third metal layer made of a metal which allows adhesion to the conductive substrate at a low temperature. As a result, the rate of reflection of light from the metal layer increases due to the presence of Ag in the metal layer. Further, the metal in the metal layer is prohibited from diffusing into the semiconductor layer, so that the semiconductor layer does not absorb light. And therefore the brightness of the semiconductor light emitting device can further be increased.
