Failure Analysis Work Flow for Dislocation Identification and Characterization by Electron Channeling Contrast Imaging Using SEM and FIB

A failure analysis work flow is presented demonstrating dislocation visualization, site isolation, TEM lamella preparation and defect characterization. A novel beam control technique allows visualizing dislocations with significantly improved spatial resolution in SEM using Electron Channeling Contrast Imaging. Site-specific TEM preparation on dislocations is therefore possible. The prepared thin lamella can be inspected in the SEM using STEM to study dislocations. This is a cost effective work flow without using TEM.
