  • Publication number: 20090297988
    Abstract: A manufacturing technique of a semiconductor integrated circuit device utilizing a defect correction technique of a reflection-type mask using extreme ultraviolet (EUV) light with a wavelength of about 13.5 nm as an exposure light source is provided. An auxiliary pattern having an opening diameter finer than that of an opening pattern in which a phase defect is generated is formed in an absorption layer in the vicinity of the opening pattern. The auxiliary pattern is a pattern for adjusting the exposure light amount at the time when the opening pattern is transferred to a photoresist film on a wafer.

  • Publication number: 20090292446
    Abstract: A control apparatus of an internal combustion engine performs control to warm up a catalyst. More specifically, the control apparatus keeps a wastegate valve open when the temperature of the catalyst is less than a predetermined temperature and closes the wastegate valve when the temperature of the catalyst becomes equal to or greater than the predetermined temperature. The control apparatus executes control to increase and decrease the fuel injection quantity such that the internal combustion engine alternately switches between lean burn and rich burn when the wastegate valve is closed. Accordingly, rich gas and lean gas can be reliably mixed in the catalyst, and CO can be reliably combusted in the catalyst. Therefore, the catalyst can be promptly warmed up while CO, HC, and the like can be appropriately suppressed from flowing through the catalyst.

  • Patent number: 7603981
    Abstract: If improper fuel (light oil or kerosene) is mixed into fuel (gasoline) supplied to the engine, a knock limit of an ignition timing is retarded. Based on such a characteristic, every when knocking is detected based on a detection signal from a knock sensor, the ignition timing is stored as the knock occurring ignition timing and the ignition timing is retarded by a predetermined amount. After repeating the above processes, it is determined whether the knock occurring ignition timing is retarded more than a determination value (for example, a retarded limit value of the knock occurring ignition timing in a case that proper gasoline is served). When the knock occurring ignition timing is retarded more than the determination value, it is determined that the improper fuel is mixed in the fuel.

  • Patent number: 7582921
    Abstract: In a masking pattern (a) for patterning word and data lines, length is changed between adjacent word lines so as to be shifted from each other at their tips, and furthermore, the tip of each word line is cut obliquely. It is thus possible to prevent the resist pattern from separation and contact of adjacent patterns. Consequently, it is also possible to prevent break failures of patterned lines and short failures between those patterned lines.

  • Publication number: 20090198434
    Abstract: A cylinder causing an abnormal air-fuel ratio is specified. Injection ratio changing control for gradually changing a ratio between command injection quantities of two injectors of the abnormal cylinder while keeping the sum of the command injection quantities of the two injectors constant is performed on the abnormal cylinder. If the injection ratio changing control is performed under the same condition, a changing behavior of the actual sum injection quantity of the two injectors varies and a changing behavior of the air-fuel ratio varies depending on which one of the two injectors is abnormal. Therefore, the abnormal injector out of the two injectors is specified using a learning value of an air-fuel ratio feedback correction value based on an output of an exhaust gas sensor.

  • Publication number: 20090055079
    Abstract: An abnormality diagnosis apparatus for an internal combustion engine includes an abnormality diagnosis unit, an other fuel contamination determination unit, and a misdiagnosis prohibition unit. The abnormality diagnosis unit determines whether there is an abnormality in a fuel system based on an output from an exhaust gas sensor mounted on an exhaust duct of the internal combustion engine.

  • Publication number: 20080250383
    Abstract: A mask pattern designing method capable of achieving the reduction in the increasing OPC processing time, shortening the manufacture TAT of a semiconductor device, and achieving the cost reduction is provided. An OPC (optical proximity correction) process at the time when a cell is singularly arranged is performed to a cell library pattern which forms a basic structure of a semiconductor circuit pattern in advance, and a semiconductor chip is produced using the cell library pattern to which the OPC process has been performed. At this time, since the cell library pattern which has been OPC-processed in advance is influenced by the cell library patterns around it, the correction process thereof is performed to the end portions of the patterns near the cell boundary. As particularly effective OPC correction means, the genetic algorithm is used.

  • Publication number: 20080094616
    Abstract: A surface defect inspection apparatus in accordance with the present invention is a surface defect inspection apparatus 500 which includes a tested object 40 a multi-layer film is formed on the surface thereof, and an illumination portion 5 which irradiates an illumination light 6b generated by the illumination lamp 41 onto the tested object 40 so that the image of the tested object irradiated with the illumination light 6b to detect a surface defect of the tested object 40 is visually observable by an observer 49. A wavelength distribution of the illumination light 6b is corrected so that the light intensity is substantially constant with respect to the wavelength sensitivity characteristics of the human eye. In accordance with the present invention, in a case of inspecting a tested object formed with a multi-layer film, even with a difference in film thickness in lower layers, unevenness in brightness or color of the surface hardly occurs, whereby it is possible to improve the detection accuracy of defects.
