Title: Semiconductor laser device and manufacture thereof
Inventor: MOGI NAOTO
IPC: H01L21/205
Filed: 1983-09-22
Abstract: PURPOSE:To contrive to improve the reliability by enabling the generation of the effect of a built-in waveguide even when a clad layer between an active layer and a current block layer is thickened by a method wherein the impurity concentration of the p type clad layer is controlled. CONSTITUTION:A part of a p type clad layer 14 under a stripe groove is made as a p type layer having a lower concentration than the other part, and made to have a large refractive index. Therefore, it becomes unnecessary to penetrate the light quided by the active layer 13 to the current block layer 15 in order to allow the effect of a built-in waveguide. In other words, the light guided by the active layer 13 becomes sensitive to the difference in refractive index due to the difference in impurity concentration in the clad layer 14, and is guided to the region immediately under the stripe having a low p type impurity concentration in the direction horizontal to the junction surface, therefore can generate the effect of a built-in waveguide even when the thickness of the layer 14 is increased. As a result, the distance between the layer 13 and the surface of crystal growth can be increased, resulting in the improvement of the reliability.

Filed: 1982-10-08
Abstract: PURPOSE:To balance flows of a molding material in a cavity, by opening a gate at a part of the cavity in the manner of being integrated with a mating surface of an upper mold and a lower mold. CONSTITUTION:A resin fed under pressure through a runner 4 flows into a lower-side recess 11 of the lower mold 2, and simultaneously flows into an upper-side recess 12 of the upper mold 1. The resin is then poured into the cavity 3 through the gate 10 at uniform speed and in the same direction from above and below a lead frame 7. Since the resin flows into the cavity 3 in the condition of being uniformly distriuted to the part above the frame 7 and the part below the frame 7, the flows of the resin at upper and lower part of the interior of the cavity 3 are balanced. Accordingly, the problem of upward bending of the frame 7 due to unbalanced forces exerted in vertical directions and other similar problems can be obviated, and generation of voids or the like due to flows of nonuniform speeds can be prevented from occurring.
