Patent JP-H0328913-A (JP)
Title: Semiconductor integrated circuit
Inventor: NAKAMURA KAZUO
IPC: G06F1/12
Filed: 1989-06-26
Abstract: PURPOSE:To cope with a high speed clock by detecting the phase difference between a lst clock and 2nd clock which is produced by a clock generator based on the delayed 1st clock, and controlling the delay time. CONSTITUTION:An original clock SL1 applied to a voltage control delay element 23 is delayed and applied to a 1st clock generator consisting of a waveform shaper 4 and a clock driver 5. Thus an internal clock CL2 is produced and applied to the other end of a phase comparator 20. Then the CL2 is controlled so that it has the phase difference of 360 deg. (1 cycle) to the CL1. The controlled CL2 serves as a reference clock for the action of a CPU internal circuit 9 and is applied to the flip-flops 10. At the same time, the CL1 is applied to a clock terminal with no intervention of a CPU chip 1. As a result, no phase difference is produced between the 1st and 2nd clocks and the cycle of the 1st clock can be reduced down to the sum of delay times of an output latch 7 and an output buffer 8. Then it is possible to cope with a high speed clock.

Filed: 1992-05-29
Abstract: PURPOSE:To accurately control width of a through-groove and thickness of a thinner area surrounding the groove without requiring diffusion to form the through-groove to a semiconductor substrate by the etching process. CONSTITUTION:A semiconductor acceleration sensor 100 is provided with a through-groove 12a and a thinner area 12b formed by etching a P-N type semiconductor substrate 10.

Title: Exposure method
Inventor: HONDA TOSHIYUKI
IPC: H01L21/30
Filed: 1987-07-02
Abstract: PURPOSE:To increase the number of device chips, which can be provided from one sheet of a wafer, by blinding either region of a device pattern, which is formed on A reticle, or a wafer alignment mark region for direct drawing, of a charged beam, exposing only the pattern of the other region, and performing said operations in the predetermined sequence. CONSTITUTION:In an exposure sequence A, a wafer alignment mark 103 for direct drawing of a charge is blinded as shown by a shaded area. The blinding position is blinded by specifying the positions of a-a'-d-d' with the distances from the center of a reticle. Thus the outer parts from the center are blinded. Only a device pattern region 102 is exposed on a wafer 201 in the predetermined sequence by using the reticle 101, which is blinded in this way. In an exposure sequence B, the device pattern region 102 is blinded, and only the four water alignment marks 103 for direct drawing of the charged beam are exposed on the wafer 201 in the predetermined sequence. Thus the exposure can be performed at the desired positions of the wafer 201.

IPC: B23K9/167
Filed: 1979-12-18
Abstract: PURPOSE: To obtain uniform penetration in butt welding of an object material using pulse current in atmosphere of inert gas by reducing the current value stepwise from the beginning of welding.  
     CONSTITUTION: Under a state where a normally open contact LRX is not closed, base current Cb is fed for a fixed time between the materials to be welded. When the normally open contact LRX is closed, a relay LR2 is closed through normally closed contacts LR3, LR4, and at the same time, a timer TM is closed. Then, a welding pulse current signal is outputted from a current setting device, and pulse current Cp 1  flows between the welding torch and material to be welded. When a timer TM2 is closed and the relay LR3 is also closed, the relay LR2 is relased and pulse current Cp 2  is made to flow. After welding is made by pulse current Cp 3  in the same manner, a limit switch LS1 works to release the relay LR4 and welding is completed.

Abstract: PROBLEM TO BE SOLVED: To provide a data file approximate to user's demand though a data file completely matching with the user's demand does not exist at the time of retrieving a data file by setting a retrieval condition by interaction with the user. SOLUTION: When a condition storage means 8 temporarily stores plural pieces of input data as the retrieved condition, a data retrieval means 5 retrieves the data file matching with the retrieved condition from a data base 6. When the number of this retrieval is '0', an interaction control part 4 successively changes plural pieces of stored data in the condition storage means 8 to detect the retrieval condition whose number of retrievals is not less than '1' and a data output device 7 outputs this retrieval condition, whose number of retrievals is not less than '1', to the user. Thus, though the data file completely matching with the user's demand does not exist, the data file approximate to the user's demand is provided.

Abstract: PURPOSE: To remove gallium sticking to a substrate subjected to liquid phase epitaxial growth from a solution using gallium as a solvent, without exerting any undesirable influence upon the substrate by using an etching reagent containing phosphoric acid, acetic acid and nitric acid.  
     CONSTITUTION: A treating liquid is obtained through mixing phosphoric acid, acetic acid and nitric acid at, for example, 5:4:1 in volumetric ratio, and a substrate for which an epitaxial layer of III-V groups compound like GaP is formed according to liquid phase epitaxial process using Ga as a solvent is soaked in said treating liquid kept at room temperature. Ga, if sticking, will react violently to the treating liquid and is thus eliminated within a few minutes to thirty minutes or so according to the quantity contained. In this case the GaP substrate also comes in contact with the treating liquid, however, the GaP substrate itself scarcely reacts to the  treating liquid, and the surface of formed epitaxial layer keeps the same condition as it was at first.
