Title: Method of manufacturing highly reliable flush type laser diode
Inventor: KIMU SANNBE
IPC: H01S5/00
Filed: 1990-08-31
Abstract: PURPOSE: To improve the manufacture yield of laser diodes and to improve an important performance index or the like by naturally dissolving a surface near an active layer exposed and damaged at high temperature in a secondary liquid-state epitaxial growth process, with which a current shield layer is prepared, without any artificial operation. CONSTITUTION: A vertical messa, of which the active layer is projected, is prepared so as not to engrave but to leave an InGaAsP active layer 6 while using the engraving solvent of hydrochloric acid for selectively engraving only a P-InP clad layer 5 and an n-InP intermediate layer 7. In order to balance the projecting active layer section with the solvent to be contacted in the case of secondary liquid-state epitaxial growth, over saturated solvent in comparison with a flat section is required so that only the projecting section of 2 can be dissolved out even in the case of balanced or a little over saturated solvent. Therefore, the surface of the active layer exposed under the high temperature and damaged by heat is removed and the current shield layer is grown.  At such a time, since the condition after re-dissolving is made a little different corresponding to the over saturation degree and contact time of the solvent, it can be sufficiently regulated. When dissolving the projecting active layer surface again, one hole of a graphite board for liquid-state epitaxial growth is allocated to the solvent for re-dissolving.

Abstract: PURPOSE:To prevent a reed switch from being damaged while it is manufactured or used, by providing a separation layer of a viscous substance between the outside surface of the switch and a filling material when embedding the switch with the filling material in a fitting hole. CONSTITUTION:A separation layer 13 of a viscous substance having a flowing property is provided on the entire outside surface of a reed switch 8 so that the separation layer having a thickness larger than the deformation which a filling material 7 undergoes when it is cooled is located between the switch and the filling material. Even if the filling material 7 is deformed when it is cooled, the viscous substance flows and moves to keep a pushing force from being caused due to the deformation of the filling material. A strong compressive force is thus prevented from locally acting to damage the switch 8.
