WAFER INSPECTION SYSTEM AND WAFER INSPECTION EQUIPMENT THEREOF

摘要

A wafer inspection system and a wafer inspection equipment thereof are provided. The wafer inspection system includes a susceptor device, probe card, and bridge module. The susceptor device includes a susceptor unit for placing a wafer under test. The probe card includes a probing portion and conducting portion. The conducting portion is disposed at the periphery of the probing portion and has a contact surface. The bridge module includes transmission units extended upward, positioned adjacent to a wafer placement area, and coupled to the susceptor unit. When the probing portion comes into contact with a testing point of the wafer, the contact surface of the conducting portion gets coupled to the transmission units to transmit a test signal to the probe card via the transmission units and conducting portion and thus form a test loop. Thus, the test loop path can be shortened and the accuracy of signal transmission and inspection can be enhanced.
