IS-350
Scanning Acoustic Microscopy
The IS-350 is the versatile workhorse in the InsightScan family of acoustic microscopes. Its large sample holder and scan area, high spatial resolution, fast acquisition speed and large bandwidth make it a powerful lab instrument for high resolution R&D applications and at the same time a perfectly suitable instrument for high volume quality control in production environment.
Why Scanning Acoustic Microscopy?
Defective or underperforming semiconductor devices often show severe package assembly issues like delamination, at various interfaces: : resine/die, resine/paddle and resine/frame, and also the embedded particules into the resine.
Scanning Acoustic Microscopy an easy way of inspection of such defects.

Why lock-in Thermography?
Defective or underperforming semiconductor devices often show an anomalous distribution of the local power dissipation, leading to local temperature increases. The ELITE utilizes Lock-in IR Thermography (LIT) to accurately and efficiently locate these areas of interest.
Lock-in Thermography (LIT) is a form of dynamic IR thermography which provides a much better signal-to-noise ratio, increased sensitivity and higher feature resolution than steady-state thermography. LIT can be used in IC analysis to locate line shorts, ESD defects, oxide damage, defective transistors and diodes, and device latch-ups. LIT is performed in a natural ambient environment without requiring light-shielding boxes.
Package Analysis requirements – the Electrical fault isolation solution
Current package analysis is reaching limits in term of sensitivity. Whereas Xray only provide visualization solution, SAM (Scanning Accoustic Microscope) being limited to dislocation, only liquid crystal aimed to do some electrical EFA; being 1000x less sensitive than Thermal lock-in.
ELITE is the most sensitive solution for electrical fault isolation on package.
In the case of 3D package, ELITE is also required to identify die localization, especially if boundary scan is broken

Silicon Analysis value
ELITE’s high sensitivity to low resistive defect enable to allow Electrical Fault Analysis (EFA) to be complemented with an easier, direct access solution to your shorts.
ELITE is enabling complement solution for standard EFA solution, extending detection potential, enabling ease of use detection – thanks to direct access to defect.
Thermal Mapping Value
ELITE is also providing contact less absolute temperature mapping. ELITE is able to achieve highest sensitivity and reliability thermal mapping characterization.
Value is to access real time visualization of your electrical component heating – localize dissipation, helping calibrating the temperature control of your device, support design improvement for enhanced reliability, etc…
ELITE’s Flexible configuration
The ELITE is completely configurable to meet our customers’ needs. It is available as a portable standalone configuration or as an add-on to an existing probe station.
ELITE is available with either a single lens and camera configuration or with the flexibility of a 4-position turret. A variety of custom, high-quality, MWIR microscope objectives are available including: 28mm wide angle, 1x, 2.5x, 5x, and 10x yield an effective magnification of 20x, coupled with the 15um pixel pitch of the 640 InSb camera…
Best sensitivity & resolution solution
Beside the exelence of its optical solution, thanks to its lens & low noise camera, ELITE’s is using most advanced lock-in application.
The higher the lock-in frequency, the higher the resulting spatial resolution. However, the higher frequency tends to reduce significantly the thermal emission to be detected. This is a limitation for many LIT systems. ELITE overcomes this limitation by offering a unique system architecture in which higher frequency LIT data can be accumulated for an "unlimited" amount of time. Data resolution improves the longer data acquisition continues.
The longer the system acquires data, the better the sensitivity. This is particularly valuable when attempting to acquire data at very low power levels or when one must acquire data from a weak failure mode.
