Wafer Testing is a crucial process in the semiconductor manufacturing industry. It involves evaluating the electrical performance of silicon wafers after they have been fabricated but before they are cut into individual chips. This testing helps identify any defects or issues in the integrated circuits, ensuring that only high-quality products move forward in the production process. During Wafer Testing, specialized equipment measures various parameters, such as voltage and current, to assess the functionality of the circuits. The results guide manufacturers in making necessary adjustments or improvements, ultimately enhancing the reliability and performance of the final semiconductor devices.
