Methods for processing a semiconductor wafer using non-contact electrical measurements indicative of at least one tip-to-tip short or leakage, at least one via-chamfer short or leakage, and at least one corner short or leakage, where such measurements are obtained from cells with respective tip-to-tip short, via-chamfer short, and corner short test areas, using a charged particle-beam inspector with beam deflection to account for motion of the stage
