英文摘要	PURPOSE:To lower resistance, and to obtain the semiconductor laser operating at low threshold currents by replacing an InP layer with an InGaAsP layer. CONSTITUTION:A second N-InGaAsP layer 102 as an active layer and a third N-InGaAsP layer 303 are formed on a first N-InGaAsP layer 301 in succession through a liquid growth method, etc. The forbidden band width Eg2 of the layer 102 is made smaller than the forbidden band width Eg1, Eg3 of other layers 301, 303 at that time because currents are to be concentrated to an active region. One parts of the layers 301, 102, 303 are inverted into a P type through a diffusion method to form a P type diffusion region 104. Accordingly, resistivity is lowered and the stable laser of a lateral mode can be obtained by low threshold currents, and processes such as complicate twice growth are not required for manufacture, and yield on manufacture can be improved remarkably.
