AI-generated Summary: Wire bonding damage occurs during the assembly of bare die or wafer IGBTs when improper bonding conditions cause defects such as misaligned bonds, chip surface scratches, or cracks. Excessive bonding stress can damage cells visibly or internally, affecting device performance and reliability. Evaluating bonding limits by adjusting power and force ensures optimal bonding strength without damage. Careful verification of bonding conditions improves yield and prevents failures like turn-off malfunctions caused by localized damage.

AI-generated Summary: Wafer testing for IGBT chips bridges the gap between wafer-level and module-level testing by applying higher test currents closer to module conditions, improving overall module quality. Key failure modes include gate failure, detected through high-voltage DC screening to identify oxide defects, and SOA failure, identified via AC switching tests to detect transient current concentration and latch-up failures. Gate screening applies stress beyond normal operation to reduce early failures and ensure long-term reliability. L-load AC screening rejects chips prone to latch-up by simulating switching conditions, enhancing yield and reducing costs in module manufacturing.
