6 FAQs about [Capacitor device failure analysis]

What are the advances in capacitor failure analysis?

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.

What is the use of capacitor in a failure analysis lab?

Useful to give quick result in failure analysis lab with limited resources. Solve short or open related defects related to capacitor structures. Capacitor is one of the most basic passive components on any integrated circuit (IC) chip, such as memory, mixed-signal, or radiofrequency (RF) devices.

What is failure analysis of integrated capacitors?

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.

What causes a capacitor to fail?

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.

Which type of capacitors are used in FEOL & BEOL failure analysis?

Do capacitor defects contribute to infant and latent failures in integrated circuits?

Capacitor defects significantly contribute to infant and latent failures in integrated circuits. This paper will address methods of locating capacitor defects and root cause determi-nation.
