Due to the silver migration of ceramic capacitors, the electrolytic aging breakdown of ceramic capacitors has become a very common problem. The conductive dendrite formed by silver migration can increase the leakage current locally, which can cause thermal breakdown and break or burn down the capacitor. The phenomenon of thermal breakdown
It can be perceived that analytical methods have been rarely utilized for the problem analysis due to the certain complexities induced by multiple DGs and CBs, different categories of DG as well as multi-objective consideration in the mathematical formulation of the objective functions.

Advancements in failure analysis have been made in root cause determination and stress testing methods of capacitors with extremely small (approximately 200 nm) defects. Subtrac-tive imaging has enabled a non-destructive means of locating a capacitor short site, reducing the FIB resources needed to analyze a defect.
Therefore, failure analysis of integrated capacitors is the key to identify the root cause but, on some cases, is also a challenging task. Three case studies were discussed that includes the FA approaches and techniques that were utilized to understand the defect sites.

Keysight Technologies’ failure analysis team determined the root cause of these failures to be voids in the capacitor dielectric layer. The voids allowed the propagation of metal into the dielec-tric layer. This metal migration led to latent failures in the field.
The OEM tested the break-down of the capacitors using test structures that were not made with the same design and did not include the seams. Therefore, stress test boards were developed to test a total of 192 undamaged devices in parallel.
All the failed capacitors detected, seven in total, were submitted to thorough failure analysis investigations (electrical measurements, infrared thermography and microsections). This analysis confirmed that the failure mode of all failed capacitors was an electrical short-circuit.
