英文摘要 | PURPOSE:To make it possible to grow excellent epitaxial layer on which a defect is hardly generated by a method wherein an Al mixed crystal layer is crystal-grown on the substrate with crystal growth speed 4Angstrom /sec or below having roughened surface using an Al-containing organic metal chemical vapor growth method. CONSTITUTION:An active layer 44, consisting of undoped AlyGa1-yAs is epitaxially grown on an n-clad layer 43, having a trapezoidal cross-section, on a mesa protrusion 42. When a current block layer 46, consisting of n-type AlxGa1-xAs of the same composition as the n-type clad layer 43, is epitaxially grown using an MOCVD method, the relation between the value x (atomic ratio), namely, the value (x), with which no defect is generated in epitaxial growth against Al content, in other words, an oxide is not generated, and vapor- growth speed g.r. is calculated, and the region smaller than the straight line g.r.=-20x+13, in other words, the slunt-lined region on the left side of the diagram is obtained. As a result, the growth speed g.r. can be suppressed to 4Angstrom /sec., because the mixed crystal ratio (x) of Al is x approx.<0.45 in general. |
