  • Patent number: 7754400
    Abstract: A method and apparatus is provided for determining an acceptable reticle tolerance for a reticle used to produce an integrated circuit layout. The method begins by specifying a wafer target CD and a wafer CD tolerance for the integrated circuit layout. A reticle target CD is provided for the reticle that is producing the wafer target CD. A critical reticle pattern pitch is selected for the reticle target CD. The critical pattern pitch defines a relationship between the wafer CD and illumination dose exposing the reticle for producing the wafer CD which exhibits a maximum gradient. For the critical reticle pattern pitch, a relationship is established between wafer CD and a deviation from the reticle target CD that arises from use of different illumination doses. From the relationship between wafer CD and the deviation from the reticle target CD, a reticle target CD deviation interval is identified that gives rise to the wafer CD tolerance that is provided.

    Abstract: A mechanism for optimizing insulin infusion rate of a CSII pump for each patient. A continuous subcutaneous insulin infusion therapy uses a continuous subcutaneous insulin pump, which includes: determining a circadian variation curve representing sympathetic nerve activity and that represents parasympathetic nerve activity of a target patient; acquiring an inflection point of each of the circadian variation curves representing the two types of nerve activity; detecting a time that corresponds to the inflection point; and employing the time as a point at which the insulin infusion rate of the continuous subcutaneous insulin infusion pump is changed.

  • Publication number: 20080054260
    Abstract: A wafer test is performed to a wafer, and then a protective film is applied to part of a chip surface of each good chip other than terminals. For defective chips, a protective film is applied to an entire chip surface as well as terminals and, while keeping that state, a burn-in test is performed, thereby cutting off power supply and signal application to defective chips before burn-in test. Moreover, when a chip includes a self-test circuit to judge whether the chip is good or not and the chip is judged to be defective, the function of stopping an internal operation of the chip may be provided or a judgment signal may be transmitted to a burn-in test apparatus, thereby stopping power supply and signal application from the burn-in test apparatus. Thus, power supply and signal application to a chip judged to be defective after burn-in can be cut off.

  • Patent number: 7325225
    Abstract: It is important to assess and reduce errors that arise in mask correction techniques such as optical proximity correction. A preliminary mask is obtained using an OPC model. An etched wafer is created from the preliminary mask using lithography, and first and second critical dimensions (CD) are measured on the wafer and. An edge placement error (EPE) is determined that corresponds to a difference between a measured value and a desired value of the second CD. These steps are repeated for a plurality of different values of the first CD, and of for each of the values of, the measured value of the second CD is correlated with its corresponding value on the mask as predicted by the OPC model. ? difference ?CD is obtained between the difference of the mask CDs calculated by interpolation of wafer CD measurements and by OPC model predictions and is transformed into an OPC model error.
