Title: Semiconductor laser optical switch
Inventor: ODAGIRI YUICHI
IPC: H01S5/00
Filed: 1985-12-27
Abstract: PURPOSE:To make the temperature control of a semiconductor laser gentle, and make the amplification of a light input and the operation in a wide range of wavelength possible, by constituting a semiconductor laser in the manner in which an electrode is divided with a groove perpendicular to the direction of a resonator axis, and a high resistivity region whose depth does not reach an active layer is arranged in the semiconductor layer directly under the groove, and coupling the laser element with an optical fiber of input and output. CONSTITUTION:A p-InGaAs cap layer 14 and a p side electrode 16 are divided into two parts along a resonator axis by arranging a groove 17, and constitute electrodes 18 and 19. In order to make a region 30 directly under the groove 17, highly resistive, the most part of crystal in the cap layer 14 and a clad layer 13 of low refraction is destructed. Then the electrodes 18 and 19 operate almost independently, because the groove 17 is high resistive, so that a current is not injected into an InGaAsP active layer 12 directly under the groove 17. Accordingly, the dimension of a saturable absorption region which is a cause of hysteresis and differential gain characteristics in the input-output characteristics of light can be easily controlled by a current injection amont. A semiconductor layer 1 changes the state from OFF to ON by a small light input for the wavelength of a light input signal 20. At the time of laser oscillation, the loss in the saturable absorption region rapidly decreases by the injection of light, and the gain exceeds the loss on the whole. Thus a large light output can be obtained.

Title: Semiconductor device
Inventor: URABE JUNICHI
IPC: H01L29/80
Filed: 1991-11-12
Abstract: PURPOSE:To improve the transmission conductance of a field-effect transistor without sacrificing the breakdown voltage by a method wherein a band gap difference between different kind semiconductor crystals is properly selected. CONSTITUTION:A drain electrode 12 and a source electrode 13 are so provided as to have a hetero-junction plane 17 between themselves in parallel with each other. Gate electrodes 14 are provided vertically to the hetero-junction plane 17. Band gaps are predetermined in such a manner that the potential energy of a semiconductor crystal region 16 is made larger than the potential energy of a semiconductor crystal region 15 by, for instance, changing the concentration of AlAs. Therefore, in accordance with the law of energy conservation, an electron receives a kinetic energy corresponding to the mutual potential energy difference when the electron passes through the hetero-junction plane 17. As a result, the saturation speed of the electron between the pair of the gates is increased accordingly. As a transmission conductance is proportional to the saturation speed, the transmission conductance is increased by the increase of the saturation speed give by this structure.

Title: Semiconductor device
Inventor: NAGAI TAKAYUKI
IPC: H01L29/78
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To make a practical gate width larger without worrying about the contamination of semiconductor wafers by forming rectangular grooves in the gate. SOLUTION: Grooves 1 of a specified depth are formed in a part to be a gate in a direction of perpendicular to the gate width. On this occasion, a plurality of grooves to be parallel to one another are formed as grooves 1. At this time, the grooves 1 are formed only under the gate electrode, and as a result of this it becomes possible to prevent a leakage current etc., caused by crystal defects in source/drain regions. Next, a gate electrode 4 is formed. At this time, the polysilicons of the gate electrode 4 are formed on the side and bottom surfaces too of the insides of the rectangular grooves 1, and fill the insides of the grooves. Accordingly, the width of the gate increases practically. After that, active regions 5 (drain and source regions) are formed.  Consequently, rectangular grooves are formed in a direction parallel to the direction of a current flowing in a channel between the source and drain regions (in a direction perpendicular to the gate width).

Thought the high viscosity oil is discharged into a low pressure space side from a high pressure space side through the communication passages 50 and 51, the discharge quantity is controlled according to the throttle area of a solenoid valve 52 whose throttle opening degree is controlled according to the traveling condition such as car speed. Therefore, the transmission torque characteristic proper for the traveling condition can be automatically controlled.
