Abstract: PURPOSE:To enable the composition of an active layer to be detected whether it is different from the essentially desired composition or not, by empolying a series of processes in which the layer, which has the same composition as that of the active layer and is thicker than that thereof, is formed on a double hetero junction, and the X-ray diffraction of the layer is then analyzed. CONSTITUTION:A double hetero junction structure section consisting of a buffer layer 102, a clad layer 103, an active layer 104 and a clad layer 105 is formed on a substrate 101, a current-carrying layer 106 and a cap layer 107 are then in turn formed on the clad layer 105. Subsequently, a same composition layer 108, which has the same composition as that of the active layer 104 and is thicker than that thereof, is grown under the same growth conditions as that of the active layer 104. After the growth being completed, the X-ray diffraction is performed about the same composition layer 108 to evaluate the degree of lattice mismatching, i.e. the composition thereof. Since the composition of the layer 108 represents the same composition as that of the active layer 104, the difference of the composition and the like resulting from the abnormal operation of a film grown system and the like can be found based on the obtained evaluation.
