SEMVision G7AP Defect Analysis

Advanced packaging is becoming a critical enabler of system-level performance, but it also raises the cost of process excursions and missed defects. Across wafer-level packaging, die-to-wafer and wafer-to-wafer bonding, hybrid copper bonding, thermocompression bonding, HBM DRAM stacking, and heterogeneous integration, manufacturers must manage increasingly complex structures, new materials, thicker and more warped substrates, and challenging interfaces. These conditions create defect review and process control requirements that conventional SEM-based review systems were not designed to handle, while packaging-specific contamination and resin outgassing can further impact imaging consistency and tool availability in high-volume manufacturing.

The SEMVision^™ G7AP (Advanced Packaging) is a purpose-built eBeam defect review and characterization system developed specifically for advanced packaging applications. It combines automated high-resolution imaging and classification with specialized handling for non-standard wafers and substrates, including silicon, glass, and sapphire formats with thickness and warpage beyond the range of standard defect review tools. Features such as automatic thickness detection, Z reconfiguration, precision navigation correction, high depth-of-focus imaging for deep trenches and high-aspect-ratio features, and eTilt with full azimuth control help deliver accurate site landing and enhanced defect visibility across demanding advanced packaging structures. Integrated contamination control and active resin outgassing management further support stable imaging performance and high system availability.

Within the SEMVision portfolio, the G7AP extends the proven G7 imaging and automation foundation to the full spectrum of advanced packaging defect review requirements. It complements Applied Materials’ broader defect review and process control capabilities by bringing automated review, on-tool classification, and specialized advanced packaging imaging into a single platform tailored for these emerging applications. As advanced packaging architectures continue to evolve, the SEMVision G7AP is designed to help customers scale inspection and analysis strategies with a flexible, production-oriented solution that supports both current requirements and future process development needs.
