Abstract

This paper highlights the use of nanoprobing as a crucial and fast methodology for failure analysis (FA) in sub 20nm with an improved semi-auto nanoprobing system. Nanoprobing has the capability to localize as well as characterize the electrical behavior of the malfunctioning device for a better understanding of the failure mechanism. It provides a valuable guide to choose a proper physical FA technique to identify the root cause of the failure. This established methodology helps to accelerate the FA turnaround time and improve the success rate. Its application to a few of the front end of line and one back end of line issues is highlighted in the paper.
