Parametric defects are uncovered only when the failing device is operated under a specific set of operations parameters-typically a combination of voltage, clock speed, and temperature. Implementing strong yet flexible detection technology coupled with a set of advanced analytical methodologies allows for the introduction of new, dynamic applications such as Logic State Mapping (LoSM) and Dynamic Laser Stimulation (DLS). Meridian facilitates the development of the most advanced dynamic applications and techniques while maintaining the capability to isolate static faults.

Configuration & Features

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-IV 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 volt devices.

The laser scanning microscope (LSM) option transforms the Meridian into a high-resolution, high-contrast confocal laser scanning system optimized for both static and dynamic failure analysis. Static Laser Stimulation (SLS) applications such as OBIRCH, OBIC, and Seebeck Effect Imaging (SEI) identify the sources of shorts and resistive faults, complementing emission-based techniques.

The advanced Sierra user environment and analysis software package includes the ability to construct high quality, high magnification image mosaics. Individual high magnification images are acquired and then seamlessly integrated to form a high-resolution image of the device over a large field of view.
