The ability to improve yield and reliability includes detailed defect analysis. Design debugging of marginal failures can be more challenging due to voltage or timing issues within the device. Determining the root cause of parametric failure requires isolation of its actual location inside the device and the ability to access the relevant circuitry without damaging the device or obscuring the defects.
The Thermo Scientific Meridian 7 System provides visible light laser voltage imaging (LVI), probing (LVP), and dynamic laser stimulation (DLS/LADA) on sub-10 nm devices. By avoiding a requirement for ultra-thin substrates, it preserves the integrity and functionality of the device under test to provide a reliable and practical production solution.
The Meridian 7 System is available in two configurations:
- Meridian 7D System: Combined 1064 nm and 785 nm dual-SIL laser scanning microscope (LSM) system
- Meridian 7S System: 785 nm-only LSM system with optional advanced sample cooling for high-speed testing where sample thermal management may be necessary to prevent thermal runaway from altering chip performance
