Patent ID: 7355692

Claim:
A method for inspecting an electrical circuit, the method comprising: performing a first inspection, comprising: optically inspecting at least a portion of an electrical circuit by detecting light reflected therefrom, while the electrical circuit is located at a first location, thus creating a first image; and providing a candidate defect indication indicating one or more regions of the electrical circuit determined in the first inspection to contain a possible defect, wherein the one or more regions are a subset of the inspected portion of the electrical circuit; performing a second inspection, comprising: optically inspecting only the one or more regions of the electrical circuit indicated in the first inspection, by detecting fluorescence emitted by the one or more regions, while the electrical circuit is located at a second location different from the first location, thus creating at least one second image; and providing a defect indication indicating defects at the one or more regions of the electrical circuit in which a defect is detected by the second inspection.
