英文摘要 | PURPOSE:To narrow the width of an active layer under satisfactory controllability, and to suppress a decrease in the yield due to step cut in the case of a buried epitaxial layer, a buried leakage, etc., due to narrowing by forming the outside of a double channel in a forward mesa and an inside, i.e., a mesa stripe to become a light emitting unit vertically or in a reverse mesa shape. CONSTITUTION:A mesa stripe 9 including an active layer 3 and double channels 100 at both sides of the stripe are formed by etching to a part underneath the layer 3 with mixture solution of HCI:H2O2:CH3COOH. Here, an SiN film 21 to become a mask is deposited directly on a P-type InP clad 4 at the stripe 9 disposed at the center of the channel 100, while an SiN film mask 21 exists on a P-type InGaAsP cap layer 20 outside the double channel. Here, the close contact of an InP/SiN with etchant of (chloric acid + hydrogen peroxide) is excellent, side etching is small, and the stripe 9 at the center becomes a reverse mesa shape, but since a region formed through the region 20 has a higher etching speed of InGaAsP than that of InP, the side surface outside the channel becomes a forward taper. |
