Semiconductor devices can fail for many reasons, leading to wasted time and increased costs for the manufacturer. Failures can result from excess current or voltage, ionizing radiation, mechanical stress, or large increases in temperature, which are the consequence of an uneven distribution of local power dissipation.

Steady-state and lock-in thermography are techniques that allow you to detect the temperature variations that lead to device failures. Of these methods, lock-in infrared (IR) thermography (LIT) offers much better signal-to-noise ratio, sensitivity, and feature resolution than steady-state thermography. LIT can be used in the failure analysis of semiconductor interconnects to locate line shorts, electrostatic discharge (ESD) defects, oxide damage, defective transistors and diodes, and device latch-ups.

LIT is an increasingly valuable technique for locating thermal faults in a broad range of semiconductor devices. The Thermo Scientific ELITE System is a powerful LIT tool that is particularly useful when combined with the Thermo Scientific Helios PFIB DualBeam for physical analysis, creating a highly efficient workflow.
