With time-to-yield being critical to profitability, it is too costly for advanced foundries, integrated device manufacturers and fabless companies to wait until after dicing and packaging to identify the source of electrical faults. The Thermo Scientific Meridian WS-DP system enables faster defect localization by using production testers, load boards, and probe cards.
All diagnostic options from the Meridian product line are available for the Meridian WS-DP, including: LVx, emission, LADA, and OBIRCH.
The Meridian WS-DP system provides:
- Ability to identify systematic defects
- Significantly increased electrical measurement throughput
- Improved defect localization success rate
- Reduced physical analysis time
Capabilities:
- Standard InGaAs-based emission detection or
- High sensitivity extended-wavelength DBX-based emission detection
- Patented, industry-proven "Point & Click" Solid Immersion Lens (SIL)
- Rapid die-to-die indexing
- Dynamic fault coverage with high-speed ATE interface
- Laser scanning microscope (LSM) for static and dynamic analysis
- Compatibility with most popular third-party EDA applications
Laser voltage imaging
Laser voltage imaging (LVI), shows the physical locations of transistors that are active at a specific frequency on the Meridian WS-DP system.
CW laser voltage probing
Continuous wave laser voltage probing (CW-LVP) acquires functional waveform data on the Meridian WS-DP system.
Photon emission microscopy
Photon emission microscopy (PEM) on the Meridian platform is based on an optimized combination of a high sensitivity InGaAs or DBX camera and high numerical aperture (NA) aberration-corrected optics. The Meridian WS-DP system provides high-resolution through-silicon imaging for backside device analysis. Low noise and high sensitivity enable emission data with unmatched signal-to-noise ratios, resulting in rapid, transistor-level fault detection. The DBX configuration provides industry-leading results even on sub-0.5 Vdd devices.
