Title: Semiconductor laser device
Inventor: YOSHIKAWA NORIYUKI
IPC: H01S5/00
Filed: 1984-07-05
Abstract: PURPOSE:To obtain satisfactory bonding strength and suppress the occurrence of a short-circuiting phenomenon through bonding solder, by bonding a semiconductor laser chip to the surface of a projection formed on an Si submount, and making the bonding portion of the sub-mount smaller than the laser chip. CONSTITUTION:An Si wafer is provided with projections by a single etching operation, and Ni dry plating is effected. Further, deposition of Cr, Ni-Cr, Ni and Sn is carried out by evaporation. The wafer is diced to obtain Si sub- mounts 9, 10 having respective projections 11. Each projection 11 is made smaller than a semiconductor laser chip. Thus, the bonding can be ensured without allowing the peripheral portion of the laser chip around which a coating agent passes to contribute to bonding. Employment of a sub-mount in which the front edge of the flat portion of the projection is on the inner side of the front edge of the sub-mount body enables bonding of a semiconductor laser chip in such a manner that the front edge of the laser chip and the front edge of the sub- mount body are aligned with each other, so that the positioning of the laser chip is facilitated and effected accurately.

Patent JP-S6118173-A (JP)
Title: Transistor
Inventor: ISHII HIDEKAZU
IPC: H01L21/331
Filed: 1984-07-04
Abstract: PURPOSE:To enable larger electric current to be taken out, by connecting a collector electrode to a collector region between a collector contact region and a base region, and to the collector contact region. CONSTITUTION:Since there is a potential gradient between a collector contact 13 and a base region 12, an epitaxial region has the highest potential on the collector contact side while the potential decrease toward the base region 12. If a contact hole 16 is provided close to the base region 12, less collector current is sufficient to cause a Schottky barrier diode to conduct. When a part of the current injected into the collector region of an output transistor 6 through the Schottky barrier diode flows into the base regions, the base current is added to the electric current value of an electric current source 5, whereby still larger output current is enabled to be conducted. Thus, the output current in a logic circuit can be increased without increasing the power consumption or using any special process.

IPC: H03L7/18
Filed: 1985-06-27
Abstract: PURPOSE:To expand the variable range of the oscillation frequency of a voltage controlled oscillator by boosting a power supply voltage applied to a charge pump circuit in a frequency synthesizer. CONSTITUTION:After a frequency division output of the 2nd frequency divider 4 is boosted by a transformer 41, the boosted output is rectified by bridge diodes 53-56, stored in a capacitor 22 and used as a power supply for a charge pump circuit 6.

Title: Multi-selection detecting circuit
Inventor: NISHINA MASATOSHI
IPC: G06F13/00
Filed: 1988-06-08
Abstract: PURPOSE:To prevent the multi-selection of drivers by making the drivers set in the addresses except the one designated by a selection command give answers to this command. CONSTITUTION:When a selection command is given to a driver 2 from a controller 1, the selection command is decoded by a command decoding circuit 3 and at the same time an address comparator 4 compares the address of the driver 2 with the address transferred via a control circuit. For a selected driver, the address set via an address setting part 7 is coded by an address coding circuit 6 and sent to the controller 1 via a selection circuit 5 and a bus line 21. This address code is also sent to the line 21 via an OR circuit 9 even with a driver already kept under a selection state. As a result, the controller 1 detects the abnormality of the address code even in case 2 drivers are selected at one time or separately with a time interval. Thus a multi-selection state can always be detected.
