Magma EFI HiRes
Magma EFI HiRes combines two sensors into one tool. A SQUID sensor for detecting the smallest possible currents as well as a magnetoresistive sensor for getting the absolute best spatial resolution when scanning close to the current. Additionally, the EFI tool can detect dead open faults with fantastic accuracy.
Cost-Effective localization of leakages, shorts and opens in dies, device packages and PC boards
The Magma Electronic Fault Isolation (EFI) HiRes system is ultimate tool for detecting all types of static defects (shorts, leakages, high resistance opens and dead opens) at the die, package or PC board level. The Magma EFI HiRes tool combines the capabilities of two sensors to achieve unparalleled sensitivity and sub micron resolution. This allows for a single system that can handle any type of device and any type of static defect.
Full Capabilities
- Magma EFI HiRes Microscope addresses all static defects: shorts, leakages, and opens.
- 3D defect localization calculates the distance from the surface of the sample to the current path when a straight current trace is available with new software able to recreate the current path in all three dimensions.
- Package shorts are a natural fit for SQUID in Magma microscopes since magnetic fields permeate all materials, e.g. power and ground planes, silicon, molding compounds, etc.
- Die shorts are located using the HiRes sensor with better than 500nm spatial resolution. Magnetic field resolution is not limited by wavelength, but only by sensor size and scanning distance.
- Leakages with mega-ohm resistance can be found with 500nA current sensitivity. Typical failures like electromigration and dendrite formation, where high current/high voltage can heal the sample, are readily solvable with Magma microscopes.
- Open failures are found using a space domain reflectometry (SDR) technique that applies a high frequency signal (20MHz to 200MHz) while detecting the RF magnetic field generated by the current. Using this technique on SOC packages with stacked die, TSVs and interposers, open failures in the silicon devices can be localized.
- The Magma EFI HiRes comes allows for opens capabilities to be extended to one or both sensors.
