Abstract:
Concepts presented herein relate to approaches for performing substrate inspection. In one aspect, the concepts relate to detecting anomalies or candidate defects on the substrate based on contrast in images obtained of the substrate.

Claim (Index 10):
A method of inspecting a substrate, the substrate used in forming a semiconductor device, comprising:\n capturing a first image of the substrate using fluorescent light emitted from the substrate; identifying a non-uniform region of the substrate from the captured image, the non-uniform region indicating candidate defects, each candidate defect indicative of a metallic discontinuity associated with the substrate; directing darkfield illumination to the non-uniform region based on a location of one or more of the candidate defects; capturing a second image in a response to reflection of the darkfield illumination at the non-uniform region; and analyzing the second image in order to determine a likelihood of the candidate defect causing electrical failure of the semiconductor device.
