Precise Thermal Analysis and Defect Localization

Temperature Measurement Microscopes and Failure Analysis for the Semiconductor Industry

Advanced microscopy systems that locate defects, map thermal behavior, and give your engineers the data they need — non-destructively, at sub-micron precision.

Precision Instruments for Quantitative Thermal Mapping and Failure Analysis

Our product portfolio addresses the two most critical challenges in semiconductor device characterization: understanding precise thermal behavior and locating electrical defects. We also operate a full-service laboratory for organizations that need access to our capabilities without purchasing an instrument.

Non-Destructive by Design. One Setup. Every Technique.

Our instruments are built around a simple principle: maximum signal quality, minimum optical complexity. We keep the analytical path direct — no unnecessary beam splitters, relays, or folds that degrade signal. The result is higher sensitivity, faster data collection, and cleaner results at every technique.

Integrated software

Our integrated software allows you to seamlessly switch between techniques from one main pull-down menu. Our interface menu options all have the same look and feel, greatly improving the navigation and ease of use for any user.

Mount once, test everything

Place your device under test (DUT) once. All sensors, optics, and analytical techniques engage from the same central QuantumScope™ platform. Biasing stability and test conditions are fully preserved — because the DUT never moves.

Multi-sensor detection

Switch seamlessly between photoemission, MWIR thermal imaging, and laser signal injection — each sensor on its own slide-mounted stage for a direct, aberration-free optical path. No alignment drift. No technique tradeoffs.

Field-upgradeable modularity

Start with the technique your current work requires, and add capabilities as your needs grow — no new system purchase required. Our modular architecture means your initial investment is not your ceiling. Budget-constrained labs can begin with a single sensor configuration and expand in the field at any time.

Sub-micron defect localization

Our systems are engineered to resolve defects at the scale modern semiconductor nodes demand — pinpointing gate leakage, oxide pinholes, hot spots, junction defects, and via shorts with the spatial precision leading-edge failure analysis requires.

What Our Systems Detect

From photon emissions invisible to the naked eye, to thermal gradients measured in millidegrees — our instruments resolve the failures that other tools miss.

Test Services

InfraScope™ and QuantumScope™

Not ready to invest in your own system? Our Vista, California lab delivers full temperature mapping and failure analysis services using our own InfraScope™ and QuantumScope™ instruments. You work directly with the same engineers who designed and built the systems — fast turnaround, expert defect localization, and the precise data your team needs to take the next step toward root cause — without the capital investment

Over 60 Years of IR Microscopy Leadership

Our roots trace to EDO/Barnes Engineering, the inventors of infrared temperature measurement for semiconductors. We have been solving the industry’s hardest device failures since the 1960s — longer than most of our competitors have existed.

Frequently Asked Questions

Semiconductor thermal and failure analysis microscopy refers to a set of imaging and measurement techniques used to identify how and why integrated circuits and electronic devices fail or overheat. Common techniques include infrared thermal mapping, photoemission microscopy, and laser signal injection microscopy. Our InfraScope™ and QuantumScope™ systems are specifically engineered for these applications — integrating multiple techniques on a single platform so engineers can cross-correlate data without moving the sample.

We locate and characterize gate oxide failures, junction leakage, latch-up conditions, thermal hotspots, and electrically active defects that produce measurable photon emission or thermal signatures under bias. Our QuantumScope™ can identify open lines, ohmic shorts, impedance issues, leakage currents, leaky capacitors, timing errors, oxide defects, resistive vias, ESD damage, and dynamic failures — all from a single instrument setup.

Explore QuantumScope™ capabilities

Yes. Our laboratory provides access to our full failure analysis and temperature measurement capabilities on a service basis. This is the right fit for organizations with occasional analysis needs, time-critical projects, or those evaluating whether an in-house system fits their requirements.

Explore Test Services

Yes. Our systems are designed around field-upgradeable modularity — you can begin with one sensor technique and add photoemission, MWIR, or laser signal injection capabilities later, without replacing the base system. InfraScope™ systems can also be built across basic microscope, probe station, ATE docking, and portable LabWalker™ platforms. When your needs diverge from our standard configurations, we design custom mechanical platforms and analytical solutions to match.
