What is a Semiconductor visual inspection equipment?

A semiconductor visual inspection device is a device that inspects defects in wafers and semiconductor chips in the semiconductor manufacturing process by image processing. By introducing semiconductor visual inspection equipment into the semiconductor manufacturing process, defective products can be sorted at an early stage, which is expected to reduce costs and improve quality and reliability. As criteria for selecting a semiconductor visual inspection device, it is necessary to consider the diameter of the wafer, the process to be used, and the type of defect to be detected.

Application of Semiconductor visual inspection equipment

Defects detected using semiconductor visual inspection equipment include wafer distortion and cracking, scratches, foreign matter adhesion, circuit pattern misalignment, dimensional defects, and package defects. It is necessary to select appropriate semiconductor visual inspection equipment and software for each process. There is also a device that is incorporated into the semiconductor manufacturing process to automatically detect defects in order to speed up inspections and save labor.

１．Chip Defect Detection: The system detects minute defects or foreign particles on the surface of semiconductor chips. This ensures that products meet manufacturing standards and prevents the shipment of defective items.
２．Packaging Inspection: The system inspects the appearance of semiconductor packages, detecting issues such as sealing defects or package damage. This ensures the reliability and long-term performance of the package.
３．Substrate Inspection: The system inspects the surface of semiconductor substrates for issues such as wiring defects, disconnections, or contamination. This ensures the quality and functionality of the substrate.
