Title: Correcting method of photomask
Inventor: YAMAO TATSUHIKO
IPC: G03F1/72
Filed: 1984-09-14
Abstract: PURPOSE:To form a corrected window pattern on a resist film only by emitting far ultraviolet light by forming the resist film on a hard mask having a pinhole, spot emitting the far ultraviolet light to form the prescribed pattern (corrected window) at the resist film, then forming a chromium film, lifting it off. CONSTITUTION:A positive PMMA11 is formed in approx. 1mum on a chromium mask substrate 10 having a chromium pattern 1 having a pinhole 9 and far ultraviolet light 12 having 250nm of wavelength peak is spot emitted. The PMMA is scattered by emitting the light to readily remove the emitted portion. When the intensity of the light is 97mW/cm<2>, the resist removed amount is 500nm/min, and as the intensity of the light is stronger, the resist amount scattered and removed within the prescribed time increases to remove the resist in a short time. Then, the chromium film is formed, lifted off to allow the corrected chromium film 13 to remain only on the correcting of the mask pattern.

Title: Defect inspector
Inventor: HORIE SHUNSAKU
IPC: G01N25/72
Filed: 1990-07-23
Abstract: PURPOSE:To obtain an apparatus which accomplishes an inspection of deficiency in molding which requires a high skill automatically and at a high speed by detecting a temperature distribution of work after machined with an infrared camera to judge possible defect of the work. CONSTITUTION:A press operation controller 2 judges the completion of a pressing working and outputs a completion signal to an image processor 3. Work (panel) after being pressed undergoes an inspection of a temperature distribution of working heat with an infrared camera 5. Generally, the temperature distribution presents the same state in the panel of the same type after it is worked normally. A judging means comprising a display device 8 and an OK/NG judging section 14 judge whether the panel has a defect or not based on the temperature distribution as detected with the camera 5. In other works, when the temperature distribution is different from that without defect though the panel is of the same type, the panel is determined to have a defect.

IPC: G06F17/16
Filed: 1988-08-02
Abstract: PURPOSE:To obtain a processing performance which is several times as high as that of a conventional vector recurrence formula instruction by dividing a recurrence formula to two or more recurrence formulas and providing a vector recurrence formula instruction arithmetic circuit which simultaneously calculates these recurrence formulas. CONSTITUTION:At the time of execution of a vector recurrence formula instruction, each pipeline computing element performs the processing only in a part of the period and is idle in most of the period. For example, the recurrence formula A(I)=B(I)A(I-1)+C(I) (i=1 to (n)) is decomposed to two 2-skip recurrence formulas as shown in a figure (a). This figure (a) show that two 2-skip recurrence formulas can be executed in parallel. A figure (b) where the recurrence formula is decomposed to four 4-skip recurrence formulas shows that four 4-skip recurrence formulas can be executed in parallel. Thus, the degree of parallel to recurrence formulas is raised according as substitution is continued, and idle computing elements in a vector processor are used to process calculation of plural recurrence formulas in parallel, and the whole of the processing time is shortened.
