Title: Optical vapor growth apparatus
Inventor: WATANABE YOSHIO
IPC: H01L21/205
Filed: 1990-08-18
Abstract: PURPOSE:To obtain an epitaxial crystal whose thickness is uniform and whose composition is uniform by a method wherein a gas, for epitaxial growth supplied from a gas supply nozzle is decomposed by means of excitation light irradiated by an optical fiber and a decomposition product is epitaxially grown on a substrate. CONSTITUTION:At this apparatus, the temperature of a substrate 3 for epitaxial growth use is heated to 280 deg.C by using a heater 12 which has been buried and installed at the inside of a susceptor, and a gas, for epitaxial growth carried by hydrogen gas is introduced into a reaction container 1 from gas supply nozzles 4-1, 4-2, 4-3. Ultraviolet rays are irradiated from optical fibers 11 installed inside the gas supply nozzles 4-1, 4-2, 4-3. Then, the gas for epitaxial growth use flows while it is passed between inner wall surfaces 4b of the gas supply nozzles 4-1, 4-2, 4-3 and side faces of the optical fibers 11. As a result, it is eliminated that the thickness of a deposit formed on the substrate becomes largest in a position faced with the central part of the gas supply nozzles. It is possible to obtain an epitaxial crystal whose thickness is uniform and whose composition is uniform over the whole surface of the substrate for epitaxial growth.

Title: Semiconductor laser device and manufacture thereof
Inventor: ISSHIKI KUNIHIKO
IPC: H01S5/00
Filed: 1988-08-31
Abstract: PURPOSE:To make an optical waveguide near an end face large in forbidden bandwidth and to make a semiconductor laser device of this design formed in a NAM structure so as to enable the high power operation of high reliability by a method wherein a quantum well of a slanting region of an active layer is disordered taking advantage of the anomalous solid phase diffusion of impurity atoms into mixed crystal. CONSTITUTION:Light emitted from a multi-quantum well active region 10 is guided through a V-shaped disordered layer 9 near an end face and projected. And, the forbidden bandwidth of the disordered layer 9 becomes corresponding to an AlAs composition of the mixture of an well layer and a barrier layer, so that it becomes larger than the energy of the laser beam emitted from a multi-quantum well layer. Therefore, the laser beam is not absorbed by the disordered layer 9, so that a NAM structure is constituted. So that, a COD level increases at the end face and a slow deterioration of the end face caused by the oxidation promoted by the released heat due to the absorption of laser rays can be prevented, consequently an AlGaAs semiconductor laser device high in reliability at a high power operation can be realized.
