Abstract
An inspection system includes a laser light source, an optical system for laser marking that irradiates a semiconductor device with laser light from a metal layer side, a control unit that controls the laser light source to control laser marking, a two-dimensional camera that detects light from the semiconductor device on a substrate side and outputs an optical reflection image, and an analysis unit that generates a pattern image of the semiconductor device, and the control unit controls the laser light source so that laser marking is performed until a mark image appears in a pattern image.
