FIB failure analysis of memory arrays


Many modern microelectronic chips contain embedded memory arrays. A typical memory bit-cell contains several transistors. Failure of a single transistor or contact within a bit cell makes the entire bit cell inoperable. A dual-beam Focused Ion Beam (FIB) tool combines milling capability with in situ Scanning Electron Microscope (SEM) imaging, which is very… (More)
