  • Patent number: 10393801
    Abstract: The present invention provides a method and a fault isolation system for detecting errors in an integrated circuit. One feature of the present invention is using a movable second probe to scan and acquire an output signal through the vias or metal line structure of a diagnostic area along a detecting line, so as to find the fault location precisely, and another feature of the present invention is using a cutter in conjunction with the above method to narrow down the fault range. The cutter is used to electrically isolate the portion of diagnostic area step by step for approaching the fault location. This method can help to save a lot of analysis time and also makes the minor fault localization possible.

  • Publication number: 20110293861
    Abstract: A plastic hollow plate is composed of an upper plate, a lower plate, and plural ribs connected between the upper plate and the lower plate. The ribs are positioned obliquely in parallel so as to shield sunlight. And with plural inclined passages formed between every two adjacent ribs, the plastic hollow plate can allow part sunlight to pass through.
