Abstract: PURPOSE:To increase the distance between the contact surface and the surface whereon a gate electrode will be formed, to flatten the P-N junction between a gate and a cathode and to obtain a high withstand voltage GTO having excellent characteristics for the subject semiconductor device by a method wherein the contact surface, on which applied voltage in forward direction is blocked, is roughened with unevenness. CONSTITUTION:An N<+> layer 41 is provided to short-circuit a P emitter layer using a main electrode 8. The junction 12 located at the center is divided into two parts, i.e., a junction 121 which will be located directly below an N emitter layer 2 and a junction 122 which will be located directly below a controlled electrode 8, and a P emitter 5 is not existed at the section corresponding to the center junction 122, but an N<+> layer 14 is provided instead. According to this constitution, the distance x between the center junction 12 and the surface of a P base layer 3 can be formed longer than the distance w between the center junction 12 and an N emitter junction 13. On the other hand, as the width y of the space charge layer extending to the side of the P base 3 under blocked condition in forward direction was designed under y<w conditions, the above width will have y<x in this GTO device, the inverse characteristics between the gate and cathode can be improved without thinning the base layer 3 and the short-circuit between the gate and cathode can be prevented even when the flat cathode electrode plate is pressurized.

Filed: 1992-06-01
Abstract: PURPOSE:To suppress the effect of an etching stopper on the element characteristics of a semiconductor device by removing the etching stopper from an area which is exposed after a second semiconductor layer is etched. CONSTITUTION:A p-type inner clad layer 35b, etching stopper layer 36, second p-type outer clad layer 35a, and p-type cap layer 37 are successively formed on an active layer 34. Then a silicon nitride layer 45 elongated in the direction perpendicular to the plane of the figure is formed in a pattern and the layers 37 and 35a are etched by using the layer 45 as a mask. As a result, the layer 37 is removed from all areas except the areas where the film 45 is formed and the etching of the layer 35a is stopped by means of the etching stopper layer 36. Thereafter, the layer 36 is removed from all parts except the mesa-like part. Therefore, the second conductor layer can be uniformly etched.

Filed: 1988-06-08
Abstract: PURPOSE:To perform automated etching while maintaining uniformity by computing a treating time with an operating device from a characteristic line, automatically differentiating the treating time of a substrate sequentially with the progress of etching of the substrate. CONSTITUTION:Etching liquid 1 is jetted on a substrate 2, e.g., on one surface of the substrate 2, as shown by an arrow, and etching is continuously performed. A characteristic line (a) having the expression of relation Y=A+B.X (A and B are constants) is plotted beforehand based on an etching rate Y and the Si-dissolved quantity X of the substrate 2. The characteristic lien (a) is stored in an operating device 3 comprising a semiconductor and the like. When an etching depth 4 of the substrate 2 is imparted into the device 3, a treating time T=(etching depth)/(etching rate) is computed in the device 3 from the characteristic line (a). With the progress of the etching of the substrate 2, the treating time T of the substrate 2 has the different values automatically and sequentially. Thus, the etching can be automated, and the uniform etching is carried out.

IPC: G06F13/28
Filed: 1987-06-04
Abstract: PURPOSE:To transfer data at a high speed by providing a data fetching means to an output device together with a specific gate circuit. CONSTITUTION:An MPU 1 carries out the processing based on a program memory 5 and delivers the necessary data to a bus lines 2 via a data memory 3 when data are transferred to an output device 4. At the same time, the memory 3 delivers an ACK signal A. A register 4-1 fetches the data on the lines 2 by the signal A via a receiver 6-1. The device 4 fetches data from the register 4-1 via a control part 4-2 in a data fetch enable state and at the same time sets the flag of a register 6-2 at '1'. A gate circuit, i.e., an AND circuit 7 sends an end signal C to the MPU 1 based on '1' of the flag as well as '1' of the signal A. Thus data can be transferred at a high speed.

Abstract: PURPOSE:To attain a high speed interruption processing by providing interruption processing-only CPU and providing an exclusive memory area. CONSTITUTION:When interruption occurs while an operating system 1 executes a regular processing in CPUA 2, CPUB 3 and CPUC 4, the interruption processing is allocated to interruption-only CPUD 5 or CPUE 6 in correspon dence with an interruption cause. Since CPUD 5 and CPUE 6 are for exclusive interruption, a task and an instruction, which are executed at present, is not present thereon and the termination waiting generation time of the executing instruction is not present thereon. CPUD 5 and CPUE 6 use the exclusive mem ory areas 11 and 12, and by having program counters and registers in the mem ory areas the exclusive utilization is attained. Thus, they can and saving is eliminated when interruption occurs. Since the time required for the saving of the program counters and the registers is aliminated, the interruption processing is speeded up.

Title: Intake/exhaust valve structure of engine
Inventor: YAMAMOTO MICHIYASU
IPC: F01L3/20
Filed: 1994-05-31
Abstract: PURPOSE:To enlarge a valve opening area during intake/exhaust processing as well as to reduce the leakage of intake/exhaust gas. CONSTITUTION:A valve face 13 whose cross sectional shape is a circular arc is formed by rounding on the edge part of the outer circumference part of a valve head 10. A seat face 14 whose cross sectional shape is a circular arc is formed to the valve seat part of a valve seat 9 for the purpose of fitting the shape of the valve face 13. A valve opening area becomes small enough in a range where valve lift quantity is small, and rapidly becomes large accompanying the increment of the lift quantity because a contact surface between the valve head 10 and the valve seat 9 is formed in a circular arc shape. Therefore, in case that valve timing is set with due regrad to the buffer curve part of the cam of a valve system, the valve opening area in the buffer curve part is enough reduced so that the leakage of an intake/exhaust can be reduced, and the valve opening area is rapidly enlarged accompanying the increment of the lift quantity so that the enough valve opening area can be retained during intake/exhaust processing.
