Abstract: A substrate testing apparatus configured to perform a hot electron analysis (HEA) test for analyzing a stand-by failure in a substrate includes a heating chuck having a first surface configured to support the substrate and a second surface opposite to the first surface. The heating chuck is configured to heat the substrate and has an aperture passing through the first surface and the second surface. A substrate moving device moves the substrate on the heating chuck in a lateral direction. A camera is under the heating chuck and photographs the substrate, which is exposed by the heating chuck aperture.
