Overview
Advanced semiconductor devices used in artificial intelligence (AI) applications are pushing traditional latch-up testing methods to their limits.
Higher current demands and increased thermal sensitivity introduce new risks, making accurate and repeatable testing essential for reliable device validation.
This application note explains the challenges of high-current latch-up susceptibility and electrical overstress (EOS) testing, and it outlines practical strategies to improve accuracy, repeatability, and confidence in results.
Why high-current latch-up testing is more challenging
Standard latch-up testing approaches often fall short when applied to modern devices. Engineers must account for:
- Complex power sequencing
- Thermal shock and temperature stability
- High-current delivery and safe fixture design
- Device conditioning and operational modes
- Hidden parasitic structures between rails and I/O
Without proper control, these factors can lead to false positives or missed failures, undermining confidence in results.
Why integrated high-current latch-up testing helps
Thermo Scientific MK.2TE and MK.4TE ESD and Latch-up Test Systems, combined with high-current power supply options, provide:
- Up to 7 high-current supplies (125–750 A each)
- Four-quadrant operation for full latch-up detection
- Programmable turn-on and stress timing
- Integrated control, execution, and results
These capabilities enable engineers to replicate real-world conditions with precision and consistency.
