英文摘要 | PURPOSE:To improve controllability of the width of an impurity doped region by composing a diffusion controlling layer of a crystal material having a lower impurity diffusion speed than that in a second semiconductor layer. CONSTITUTION:A growing substrate is took out from a growing chamber and Zn, as an impurity, is diffused so far as it reaches a quantum well structure 3. At this time, as the Al composition ratio of a diffusion control layer 4 is smaller than that of a P-type clad layer 5, the diffusion speed of Zn in the diffusion control layer 4 becomes lower than that in the P-type clad layer 5. Accordingly, the diffusion control layer 4 acts, by using the Zn diffusion as a mask, so that Zn can't reach the quantum well structure 3 located right under the diffusion control layer 4. Then, a quantum thin wire structure 7 is formed in order to prevent disorder. At this time, the diffusion quantity in the parallel direction with a growing layer surface is determined according to the thickness of a P-type confinement layer 12. Accordingly, by setting the thickness of the P-type confinement layer 12 to be 1000Angstrom or less, horizontal extension of the diffusion can be restrained under that value and the quantum thin wire structure can be formed with good controllability. |
