Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a diagnostic device with which the operational abnormality of flow controller (mass flow controller) for controlling the flow of gas or the like at a semiconductor production device is speedily detected and the contents and factor or the like of abnormality can be estimated. SOLUTION: The flow rate detected by a flow sensor in the flow controller is supplied to a diagnostic device 5A. A predictive flow transition arithmetic part 51 arithmetically finds predictive flow transition 51a and allowable range 51b at the time of set flow change based on flow setting data 23c before and after the set flow change and the previously registered response characteristics of flow controller. A flow transition monitoring part 52 monitors the measured flow transition based on flow measuring data 21c and when the measured flow gets out of the allowable range, an abnormality detection output 52a is generated. An abnormality content judging part 53 judges the contents of abnormality while paying attention upon the predictive flow transition 51a and the measured flow transition.  Based on the abnormality detection output 52a, an alarm is issued and the contents of abnormality are displayed on the screen of monitor.

IPC: G01N21/17
Filed: 1985-02-22
Abstract: PURPOSE:To automatically perform the checking of the density of Oxide- inducing Stacking Fault (OSF) as well as improve the precision of the checking by photographing the surface of a silicon wafer by means of an image sensor through a microscope to obtain an image signal, and performing the image recognition process of this image signal based on the previously prepared signals of the standard patterns of OSFs thereby to count OSFs. CONSTITUTION:The required area of the surface of a silicon wafer 1 is photographed by an image sensor 6 through a microscope 5. The image photographed by the image sensor 6 is converted by an image processing unit to an image signal which was made two-valued with parameters of the X-Y coordinate according to a certain threshold value, and is stored in the memory of a CPU 3. On the other hand, various standard patterns of OSFs are converted to the image signals which were previously made two-valued with several parameters of the X-Y coordinate, respectively, and are stored in the memory of the CPU 3. Then, the image signal of the silicon wafer 1 is retrieved by an image processing unit 7 using the image signals of the various standard patterns and the result of the counting is stored in the memory of the CPU 3.

Abstract: PURPOSE:To safely and perfectly wash an object to be washed without corroding the membrane on the surface of the object to be washed by applying an ultrasonic wave to the object to be washed to generate heat in the object to be washed and heating only the org. alkali solvent in the vicinity of the object to be washed by this heat. CONSTITUTION:The object 4 (e.g. wafer) to be washed immersed in a solvent 10 is washed while an org. alkali solvent 10 such as monoethanolamine is heated. At this time, an ultrasonic wave is applied to the object 4 to be washed by an ultrasonic oscillator 6 to generate heat in the object 4 to be washed and only the org. alkali solvent 4 in the vicinity of the object to be washed is heated by this heat. As a result, the org. alkali solvent is not heated to high temp. as a whole and the ultrasonic wave penetrates into the fine parts of the object to be washed. By this method, the object to be washed can be safely and perfectly washed and, when a membrane is formed to the surface of a semiconductive substrate being the object to be washed, the corrosion of the membrane can be prevented.

Title: Electron gun for electron beam processing machine
Inventor: KITA HISANAO
IPC: H01J37/315
Filed: 1979-03-23
Abstract: PURPOSE: To prevent slight discharge occurring in the electron gun when processing a thick plate with electron beams, by providing a second focusing means capable of spacing the work from the lower end of a first focusing means by a distance larger than the mean free path of molecules under processing vacuum state.  
     CONSTITUTION: The distance between the work to be welded (for example, carbon steel of 100mm in plate thickness) 13 and a first focusing coil 9 is set to be more than 1.3m, for example, 2.5m, and a second beam adjusting device 21 consisting of second focusing coil 19 and second deflecting coil 20 is placed near the work 13. While evacuating a welding vacuum chamber 1 with an exhaust pump 3 to a specified degree of vacuum, the electron beam focused by the first beam adjusting device 11 is sent into the welding vacuum chamber 1 through an electron gun vacuum chamber 4, and is further focused by the device 21 to weld 14 the work 13. As a result, the degree of vacuum at point D beneath the electron gun in the chamber 1 is held nearly at the same degree of vacuum at point B even while welding. The metal vapors and gas molecules generated from the welded part 14 are sufficiently absorbed by the pump 3, so that the quantity of metal vapors and gas molecules sucked into the beam generating part in the chamber 4 through the hole in anode 8 may be decreased. Therefore, the slight discharge occurring in the electron gun may be also decreased.

Abstract: PURPOSE:To prevent the scattering of raw material powder grains to a seal weld zone to be welded by an electron beam and to prevent the generation of a weld defect by disposing metallic or non-metallic powder grains or fibers separate from the raw material powder grains for lining into a thin layer state to the part near the weld zone. CONSTITUTION:The powder and granular or fibrous body of the metal consisting of the same compsn. as the compsn. of a member (case 2, base metal 1) to be welded or the compsn. approximate thereto or the non-metal such as CaO is preliminarily put near an aperture 7 to be subjected to seal welding, for example, right under a cap 4. In other words, the powder and granular or fibrous body of the metal or non- metal which does not melt during prescribed hot isotropic pressurization treatment and is harmless even when incorporated into the weld zone in the stage of welding is made into the thin layer and is preliminarily placed to the above-mentioned part. Then there is the metal or non-metal which dose not hinder the welding right under the aperture 7 even if the lining raw material 3 is sucked through the aperture 7 to be welded in order to evacuate the inside and only such metal or non-metal is sucked and attracted near to the aperture 7. The good seal weld zone 5 is thus formed in electron beam welding.
