Laser Voltage Imaging: A New Perspective of Laser Voltage Probing

Laser Voltage Imaging (LVI) is a new application developed from Laser Voltage Probing (LVP). Most LVP applications have focused on design debug or design characterization, and are seldom used for global functional failure analysis. LVI enables the failure analysis engineer to utilize laser probing techniques in the failure analysis realm. In this paper, we present LVI as an emerging FA technique. We will discuss setting up an LVI acquisition and present its current challenges. Finally, we will present an LVI application in the form of a case study.
