Used MACTRONIX AE1-568 Fully Automated Macroscopic Inspection System

The MACTRONIX AE1-568 is a fully automated macro inspection system, categorized as standard M&I (Metrology and Inspection) equipment used in semiconductor front-end manufacturing and advanced packaging production lines.

Core Function: Macro-level Defect Inspection on Wafer Surfaces

This system is primarily designed for rapid "scanning" and visual inspection of wafer surfaces. Following critical process steps—such as photolithography, etching, thin-film deposition, or CMP—it performs a high-speed scan of the entire wafer to detect macro-scale defects, including scratches, contamination, photoresist residue, water spots, and large-area pattern loss.

Key Technical Features

Multi-angle Optical Imaging: Typically integrating brightfield, darkfield, and oblique (side-angle) illumination, the system uses light from various angles to highlight surface particles, scratches, and variations in thin-film stress, thereby enhancing defect contrast.

High-throughput Automation: Equipped with an automated wafer-handling system, it supports rapid, batch-processed scanning. Compared to high-magnification microscopes (such as the Olympus MX50), it can survey an entire wafer at significantly higher speeds.

Defect Classification and Fab Integration: Utilizing image-processing software, the system automatically identifies and classifies defects. It supports SECS/GEM communication, enabling real-time data transmission to the fab’s defect analysis system and providing precise coordinates for subsequent high-resolution review.

Summary

With its rapid macro-optical scanning capabilities and high level of automation, the MACTRONIX AE1-568 serves as a vital inspection tool in wafer manufacturing for screening critical defects and monitoring process-related contamination.
