Abstract: PURPOSE:To cut down the production cost by means of bonding all semiconductor chips simultaneously by a method wherein a semiconductor chips are arranged on the chip bonding part through the intermediary of an adhesive layer to be heated and molten. CONSTITUTION:A solder layer 4 is formed on the laser chip connecting part of each element forming region 2. The solder layer 4 is composed of tin formed on a metallic layer such as e.g. gold, nickel etc. easily adaptable to solder. A semiconductor laser chip 7 is located on the solder layer 4 while a semiconductor substrate 1 is heated by means of passing it through a tunnel furnace or inserting it into a vacuum baking furnace to bond the semiconductor laser chip 7 on the laser chip connecting part of semiconductor substrate 1 through the intermediary of the solder layer 4. Through these procedures, the production cost of semiconductor device may be cut down remarkably since all semiconductor laser chips 7 for overall element forming regions on the substrate 1 are bonded simultaneously.

Abstract: PURPOSE:To facilitate to mount each element on a heat sink by forming a plurality of semiconductor elements on a semiconductor substrate; applying a transfer sheet provided with soldering material patterns closely to the elements; heating them to transfer the soldering material onto the elements; and seperating the elements individually. CONSTITUTION:A multiplicity of soldering material patterns 12 are formed on a transfer sheet 11 made of a W plate having a poor wettability to the soldering material. Bar-shaped semiconductor substrates 13 obtained by cutting a wafer provided with laser diode elements are fixed on the sheet 11. In this case, the patterns 12 are formed slightly smaller in size than the diode elements, and are aligned with them precisely. The assembly is heated in reducing atomsphere containing hydrogen gas to a temperature high than the melting point of the soldering material so as to transfer the pattern 12 to each element. These elements are then cut off individually. The element thus obtained 13A is adhered on a heat sink 15 through the pattern 12.

Abstract: PURPOSE:To obtain a stable oscillation by forming a reverse conductivity type or semi-insulating layer on the stepwise top of the semiconductor substrate and effectively concentrating a current in an active layer in the vicinity of the step. CONSTITUTION:A P type GaAs 60 is formed on an N type GaAs substrate 2, and with an SiO2 mask is etched, and the step 13 is formed thereon. An N type Ga1-X AlX As 4, a P type GaAs active layer 5, a P type Ga1-XAlXAs 6, and a P type GaAs 7 are laminated thereon. An opening 62 is perforated at an SiO2 film 63, an electrode 64 is perforated thereat, and an electrode 65 is fitted therethrough on the substrate 2. According to this configuration, an electric current flows effectively concentrically from the electrode 64 through the rightside of the step of the P type layer 60 to the electrode 65 as designated by an imaginary line 66, and the layer 60 thus prevents branching of the current. In this manner stable oscillation can be obtained, the extension of the laser beam can be reduced, and the threshold current can be lowered. Further, the manufacturing work can be extremely performed satisfactorily.

CONSTITUTION:A step 13 inclined on one main surface is formed on a semi-insulating substrate 12. An n -type Ga0.6Al0.4As layer 14 as the first enclosure layer, an n-type GaAs layer 15 as an active layer, an n -type Ga0.6Al0.4As layer 16 as the second enclosure layer, and an n -type GaAs layer 17 as an uppermost layer are sequentially formed in liquid phase growth thereon. P-type impurity ion is implanted onto the layer 17 to form a pn junction 20 intersecting laterally the layer 15 inclined in the vicinity of the step 13. A proton H 22 is implanted using a mask 21 to form an insulator 23 reaching the layer 16. The mask 21 is removed, and ohmic electrodes 25, 26 are formed on the p-type layers 19 and 17, respectively. The irradiated light is enlcosed in the junction 20 substantially in four directions as designated by arrows.

Abstract: PURPOSE:To obtain a cap with a light-transmission window through one-time fabrication process by sealing a light-emitting device supported by a header with the cap, which consists of a transparent material and to which the light- transmission window is formed integrally. CONSTITUTION:A header 1 is shaped through injection molding under the state in which a lead frame 12 is inserted into a molding die for forming the header. A light-transmission window 9 for a cap 7 is shaped by indenting the surface and rear of a head section 8 at central sections. Consequently, sections 15, 15, to which the light-transmission windows 9 are formed, in molds 13, 14 are formed to a protruding shape, and are easy to be ground. As a result, both surfaces of the light-transmission windows 9 in the cap 7 can be shaped in an excellent optical face. With a semiconductor laser used as a light source, the cap 7 is formed by a transparent resin, and the light-transmission windows 7 are shaped integrally with the cap 7. Accordingly, the cap 7 with the light- transmission windows 9 can be shaped through one-time resin fabrication.

Abstract: PURPOSE: To simply inspect and measure whether an FFP has a symmetry or not even at the stage that it is not yet mounted on a heat sink or a header by forming a plurality of photodetectors for receiving the laser light from a semiconductor laser on the surface of a semiconductor substrate, thereby accurately positioning and bonding the chip to the substrate.
CONSTITUTION: Three PIN photodiodes PDl, PDc, PDr are disposed in parallel with a center line 6 of a semiconductor substrate 1 on the surface of a monitor region 7 of the substrate 1. A probe 9l is contacted with the surface of the photodiode PDl of the left side as seen from a semiconductor laser chip 2 side, a probe 9l is contacted with the surface of the photodiode PDr of the right side, reverse bias voltage of the same value is applied individually to the photodiodes PDl and PDr to detect the photocurrents flowed to the photodiodes PDl and PDr at that time, thereby comparing the photocurrents. If there is no difference exceeding the allowable preset range between the photocurrents, the laser is judged as having symmetry in the FFP.
