Soft defects in integrated circuits (ICs) are defined as failures when the IC is partially functional, but will not operate properly under all specified conditions - these conditions may be within or outside normal limits. To address soft defects, a laser scanning methodology termed soft defect localization (SDL) was developed that rapidly locates soft defects in integrated circuits. The SDL method evaluates the pass/fail state of a device in response to localized laser heating to successfully localize soft defects. The method operates globally by scanning the laser over the entire die to quickly isolate soft defects in a matter of minutes. The SDL imaging system and methodology will be described followed by the presentation of several examples.
