英文摘要 | PURPOSE:To enhance the manufacturing yield by disposing the peripheral edge except part of a cleaved surface of the uppermost layer of an electrode in coincidence with or inside the peripheral edge of the lower layer for supporting the uppermost layer. CONSTITUTION:A laser chip is formed of a multilayer grown layer 6 sequentially formed with a buffer layer 2 made of an N type InP, an active layer 3 made of InGaAsP, a clad layer 4 made of P type InP, and a cap layer 5 made of P type InGaAsP in a stripe shape on the main surface of an N type InP substrate A blocking layer 7 made of P type InP, a buried layer 8 made of N type InP, and a cap layer 9 made of InGaAs are buried at both sides of the layer 6. The main surface side of the substrate 1 is coated with an insulating film 10 except the electrode contact region of the layer 6. An Au layer 12 of the upper layer of an anode electrode 13 is effectively placed on a Cr layer 1 Thus, the layer 12 is not short-circuited due to the contact with a P-N junction presented on the peripheral surface of the laser chip. |
