Title: Semiconductor laser device and manufacture thereof
Inventor: MATSUBARA KUNIO
IPC: H01S5/00
Filed: 1989-01-31
Abstract: PURPOSE:To reduce a laser device of this design in threshold current by a method wherein a junction face deviation layer, which has the same conductivity type with a second clad layer and is grown on the interface of the second clad layer, is interposed between the second clad layer and a current constriction layer. CONSTITUTION:A junction face deviation layer 10, which has the same conductivity type with a second clad layer 4 and is grown on the interface of the second clad layer 4, is interposed between the second clad layer 4 and a current constriction layer 6. The lower side (shoulder interface 4b) of the junction face deviation layer 10 is an epitaxially grown interface of itself and the upper side is a P-N junction face, as the current constriction layer 6 is succeedingly formed on the grown junction face deviation layer 10, the P-N junction face has no etching pit or not oxide film and is possessed of a uniform and stable P-N junction. By this setup, a leakage current is restrained from occurring in the P-N junction face between the current constriction layer 6 and the junction face deviation layer 10, so that a laser device of this design can be reduced in threshold current.

Title: Semiconductor device
Inventor: KOBIKI MICHIHIRO
IPC: H01L21/338
Filed: 1990-01-31
Abstract: PURPOSE:To attain the enhancement of performance and reliability through lowering the operating temperature by a method wherein the thermal resistance of solder particles is lowered by filling up a via-hole with the solder particles to be forced to reflow later. CONSTITUTION:A via-hole of a via-hole type GaAs transistor is filled up with solder particles 7 of solder fine particle dispenser etc., such as AuSn etc., furthermore, the via-hole bottom part is filled up with the reflowing solder particles. At this time, the solder particles 7, if AuSu is used, reflows at about 300 deg.C. Besides, the thermal conductivity of the solder particles 7 is made higher than that of the unit bodies of the solder material to heighten the heat dissipation effect by making a high temperature conductive powder such as diamond etc., mix, fill up and reflow together with the solder fine particles. Furthermore, since this filler exists in the region making an angle of 45 deg. from a gate electrode to the rear electrode, the thermal resistance can be lowered. Accordingly, the enhancement of performance and reliability due to the decline in operating temperature can be attained.
