20250172609. Probe Testing (Renesas Electronics)
PROBE TESTING APPARATUS, PROBE TESTING SYSTEM AND PROBE CARD
Abstract: a probe testing apparatus includes a wafer stage, a temperature sensor, a temperature adjustment mechanism, and a controller. the wafer stage includes a wafer mounting surface on which a semiconductor wafer is mounted. the temperature sensor includes a temperature observation point exposed on the wafer mounting surface, and directly measures a temperature of a rear surface of the semiconductor wafer mounted on the wafer mounting surface. the temperature adjustment mechanism adjusts a temperature of the wafer stage by heating or cooling the wafer stage. the controller controls the temperature adjustment mechanism in such a manner that a measured temperature by the temperature sensor becomes a target temperature.
