Abstract:
An inspection apparatus includes a stage on which a substrate having an inspection target is placed, a probe card, a light irradiator, and a controller. The probe card has probes that supply a current to the inspection target. The light irradiator irradiates light to heat the substrate. The controller controls the light irradiator to execute uniformly heating the inspection target by the light from the light irradiator, and heating an outer peripheral portion of the inspection target by the light from the light irradiator.
