Abstract:
1. An integrated FIB/PEM apparatus for conducting failure analysis on an integrated circuit sample, comprising: an evacuated chamber having a sample holder therein, said evacuated chamber having a feedthrough therethrough for connecting an electrical stimulus to said sample, and having an electrical connection from said feedthrough for connecting to said sample; an optical beam from a light source directed into a column, said optical beam to be focused onto a sample held in said sample holder, said optical beam in said column having an optical beam axis; an optical imaging detector for detecting and imaging photon emission from said sample; an ion beam from an ion source in said column, with associated optics to direct and focus said ion beam onto said sample, said ion beam having an ion beam axis; a charged particle detector for detecting and imaging charged particles emitted from the interaction of the ion beam and the sample; and a controller for controlling said focused ion beam to perform circuit modification on said sample.
