Inventor: KITAMURA MORITATA
IPC: G01N9/24
Filed: 1991-05-21
Abstract: PURPOSE:To obtain an analysis technique capable of highly sensitively measuring density of carbon and oxygen in silicon even at a small area in the neighbourhood of the surface of a sample or with a thin film sample. CONSTITUTION:One method is to measure photo luminescence intensity A after irradiating an electron beam on a silicon sample 1, furthermore to measure photo luminescence intensity A by way of driving carbon or oxygen ion and to calculate carbon density and oxygen density in silicon from E, A. The other method is to drive carbon ion in a first area of the silicon sample 1 and oxygen ion in a second area, to measure photo luminescence intensity A1, A2 of each of the areas and to calculate the oxygen density from A1 and the carbon density from A2. It is possible to analyze a small area by contracting the electron beam, an ion beam or a beam diameter of an excitation beam and to analyze an area of optional depth by optionally setting accelerating voltage of the electron beam and the ion beam.

Title: Image recognition method and its device
Inventor: KATSUMI HIDEO
IPC: G06K9/38
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To improve the image recognition success rate by calculating again the threshold to be used for the next image recognition based on the histogram of the density data excluding those that can be clearly grasped as a part of the image to be recognized. SOLUTION: The image data picked up by a CCD camera 13 are inputted to a character recognition device 14. A character segmentation part 21 of the device 14 segments a rectangular part including a character string 12, and a binarization processing part 22 sets the proper threshold based on the histogram of a gray image to binarize it. A character recognition part 23 compares the binarized image with a prescribed character string to recognize the characters. An evaluation part 24 calculates the reliability of recognized characters. When the reliability is lower than a prescribed degree, the part of the density data smaller or larger than the threshold is eliminated from a density histogram. Thus, a new histogram is produced by a histogram production part 25, and a threshold calculation part 26 calculates new threshold from the new histogram. Then the characters are recognized based on the new threshold.

Filed: 1989-05-09
Abstract: PURPOSE:To execute built-in diagnosis and to obtain a sufficient analytic result by directly reading out the status of respective devices in a CPU in addition to the analysis of the built-in diagnosis from collected storage information when a fault occurs. CONSTITUTION:When a fault occurs due to a failure or the like in a circuit during the operation of respective devices in the CPU 1 and a part of the devices or the whole devices are disabled to operate, a built-in diagnostic analysis part 4 executes the built-in diagnosis of the fault information stored in a fault information storage part 2 through a diagnostic control part 3. In addition, the analysis part 3 directly reads out information from the device in which the fault occurs in the CPU 1 through a diagnostic path connected between the CPU 1 and the diagnostic control part 3 and executes the built-in diagnosis. Two results, i.e. a storage information analytic result and a direct reading information analytic result are reported to the control part 3, which stores these results and informs the stored results to a diagnostic operation part 5. Consequently, when information is directly read out, all the information can be observed and more sufficient analytic result can be obtained.

Title: Manufacture of compound semiconductor substrate
Inventor: KAKIMOTO SEIZO
IPC: H01L21/20
Filed: 1987-05-13
Abstract: PURPOSE:To achieve a compound semicodncutor substrate of a good crystallizability by previously partially making the surface of a substrate amorphous before the hetero-epitaxial growth of a compound semiconductor, thereby diffusively forming fine amorphous parts 3. CONSTITUTION:Using a focused ion beam 2 of Si<+>, part of a single crystal Si substrate 1 is sequentially made amorphous in the direction of A, thereby uniformly diffusively forming fine amorphous parts 3 in the shape of a spot or line. Then, GaAs is crystallized on the substrate surface, and in this early stage of an epitaxial growth, on the fine amorphous parts 3 an amorphous or polycrystalline growth part 5 is formed, while on a single crystal part 4 a single crystal growth part 6 is formed. In this growing process, the strain due to lattice constant difference or thermal expansion coefficient difference is reduced in the amorphous or polycrystalline growth part 5, so no defect encroaches into the single crystal growth part 6. Thereafter, with the complete single crystal growth part 6 as a seed crystal, a single crystal growth proceeds, whereby a complete GaAs single crystal layer 8 is formed.

IPC: H01L29/737
Filed: 1992-04-10
Abstract: PURPOSE:To reduce a parasitic leakage current to a satisfactory extent by selectively eliminating a second insulating film, exposing an outer base layer comprising a third semiconductor layer and forming a base electrode in a self- alignment fashion and enhance high frequency properties, and especially a maximum oscillation frequency by further reducing base resistance dramatically. CONSTITUTION:Formation of an outer emitter high resistor layer 7 stabilized by oxygen ion implantation reduces a parasitic leakage current flowing during the junction of an outer emitter base. Moreover, the base resistance is reduced by connecting continuously a high concentration outer base layer 8 and a collector layer 10 to an inner intrinsic base layer 4 and making an epitaxial growth based on a regrowth process and forming a base electrode 14 in a self-alignment fashion. This construction makes it possible to reduce the base resistance dramatically and enhance a current amplification factor, high frequency properties and especially a maximum oscillation frequency.
