摘要: A method for testing a substrate by using a photoemission microscope is provided which includes providing the substrate and applying a reverse bias voltage to the substrate. The method further includes detecting light emissions from a top surface of the substrate and characterizing viability of the substrate from the detection of the light emissions.
