Then, in addition to the formation of the n-ohmic electrode 11 and the p-ohmic electrode 12, a nitride semiconductor layer in the neighborhood on the left of the n-ohmic electrode 11 is not removed by an etching operation so as to be left, and a heat-dissipating part 30 which is formed to be a shape capable of coming into contact with a heat sink 40 is formed.  Thereby, it is possible to obtain a nitride semiconductor laser diode whose heat-dissipating property is improved, which restrains a rise in a threshold value and whose life characteristic can be enhanced.

Title: Multilayered wiring element and its manufacture
Inventor: DOI YASUHIRO
IPC: H01L21/768
Filed: 1994-03-08
Abstract: PURPOSE:To prevent the cracking of a top passivation film so as to eliminate the exciting cause of the aluminum corrosion of a second wiring layer by burying the second wiring layer in a second polyimide film without coating the top passivation film directly. CONSTITUTION:When a silicon nitride film 12 is deposited in a thickness of about 1.0mum by using plasma after forming first wiring 11 covering a field oxide film and having a thickness of about 1.0mum, a first project-like section 13 is formed in the film 12 at the part corresponding to the wiring 11. Therefore, a first polyimide film 14 having a thickness of 0.4mum is formed to fill up the level difference of the section 13. In addition, second and third projection-like sections B and C are respectively formed in the first polyimide film 14 and a silicon nitride film 15 corresponding to the projection-like section 13. Then the level difference between the projection-like section C and a flat section D is filled up by applying a second polyimide film 14 in a thickness of 0.4-1.0mum. While a fourth projection-like section 19 is formed in the second polyimide film 17 covering second wiring 16, the curvature of the section 19 becomes smaller than that of the projection-like section 13 and the level difference of the section 19 is small. Therefore, the cracking frequency of a top passivation film 18 can be suppressed.

Title: Constant current circuit
Inventor: IMAIZUMI MASAAKI
IPC: H03F3/343
Filed: 1985-02-28
Abstract: PURPOSE:To decrease the area occupied by an element deciding a reference current in circuit integration by using an ON-resistance of a unipolar transistor (TR) in order to decide the reference current of a constant current circuit. CONSTITUTION:A base and a collector of a TR T3 are connected, its common connecting point is connected to a base of a TR T4 and also connected to a drain of a P-channel MOS.FETTS. Further, a back gate and a source of the FETTS are connected and its common connecting point is connected to a power supply VCC. Each emitter of TRs T3, T4 is connected to common respectively. In giving a potential VC (VCC-VC>0) to a gate terminal G of the FETTS, a stable and highly accurate reference current I3 (=ISD) flows to the FETTS by using the FET at a saturated region depending on the relation between a source-drain current ISD and a drain-source potential VDS of the FETTS. As a result, the absorption current I4 has an error within + or -5% of the reference current I3 over a wide temperature range or current level.

Title: Light diffusion plate for transmission type screen
Inventor: KAWASAKI KATSUICHI
IPC: G03B21/62
Filed: 1987-02-23
Abstract: PURPOSE:To improve the performance of a light diffusion plate by adopting the effective projection area and noneffective projection area of a light diffusing material in a specific range as evaluation items. CONSTITUTION:The light diffusing material is required to be >=1.5cm<2> in the effective projection area and to be <=0.1cm<2> in the noneffective projection area. A hot spot or bright line is generated regardless of the lens shape of the transmission type screen if the effective projection area of the light diffusing material is <1.5cm<2>. The entire part of the image screen darkens and the sharpness of the video is impaired if the noneffective projection area exceeds 0.1cm<2>. Although the kind, grain size and compounding ratio of the light diffusing material are not particularly limited, the more preferable material is a crosslinked polymer essentially consisting of methyl methacrylate/acrylate/arom. vinyl monomers and having 30-300mu average grain size and glass beads having 10-30mu average grain size. The performance of the light diffusion plate is thereby improved.

The current of wire rod 6 is adjusted while the bubble chip is being operated, so as to set an optimum magnetic bias field to the package. After the operation test ends, wire rods 6 are removed from package 1. This structure requires no magnetic-bias-field setting initial coil inside of the package, so that the package can be made miniature and lightweight.
