  • SEMICONDUCTOR DEFECT INSPECTION METHOD AND APPARATUS
    Publication number: 20250093303
    Abstract: A method and an apparatus for inspecting defects in semiconductors may be incorporated in a vehicle production process. The apparatus includes an exterior inspection unit for inspecting an exterior of a semiconductor, a function inspection unit for inspecting functions of the semiconductor, a first ultrasonic inspection unit for performing a first ultrasonic inspection on the semiconductor, a pretreatment tester for performing a pretreatment on the semiconductor when the first ultrasonic inspection has been completed, a second ultrasonic inspection unit for performing a second ultrasonic inspection on the semiconductor when the pretreatment has been completed, and a cross-sectional inspection unit for inspecting a cross-section of the semiconductor when the second ultrasonic inspection shows that delamination has increased after the pretreatment.
