سلام
دارم یه متنی راجع به مدارهای VLSI می خوانم این تیکه رو دقیق متوجه نمی شم ممنون می شم کمکم کنید

Analogously, we define the critical area, A(c) i (x), for defects of type i and diameter x as the area inwhich the center of a defect of type i and diameter x must fall in order to cause a circuit failure, and by A(c) i the average over all defect diameters x of these areas.
